In this paper, we perform theoretical analysis and experiments on the Simplex Crossover (SPX), which we have proposed. Real-coded GAs are expected to be a powerful function optimization technique for real-world applications where it is often hard to formulate the objective function. However, we believe there are two problems which will make such applications difficult; 1) performance of real-coded GAs depends on the coordinate system used to express the objective function, and 2) it costs much labor to adjust parameters so (...) that the GAs always find an optimum point efficiently. The result of our theoretical analysis and experiments shows that a performance of SPX is independent of linear coordinate transformation and that SPX always optimizes various test function efficiently when theoretical value for expansion rate, which is a parameter of SPX, is applied. We also show that BLX-α is equivalent to degenerate form of SPX. Experiments show that we have something misunderstood effect of epistasis on performance degradation of real-coded GAs. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:201 HUME TO SMITH: AN UNPUBLISHED LETTER* In all probability, a newly-discovered letter by David Hume, written on 17 November 1772 and published here for the first time, was addressed to Adam Smith. Purchased in May 1982 by Kwansei Gakuin University Library, it now forms part of the Adam Smith Collection there. The vendors stated the letter was acquired from a French collector, but there seems to be no (...) other information available about its provenance. The letter itself is a brief one in which Hume urges the addressee to move to an excellent house in the New Town of Edinburgh which will be empty next Whitsuntide, one of the Scottish quarterdays or term-days, fixed for the beginning and end of tenancy and usually falling on 15 May. There is a postscript, in which Hume adds that he is enclosing an account of the importing of money into Spain that was once requested from him. This enclosure has not been traced. There is no doubt about the authenticity of the Hume letter, but there is a technical difficulty about the identity of the addressee. This is made known by a slip pasted on the foot of the letter. A suspicious mind might think of an owner doing this to enhance the value of the letter, but the words 'Adam Smith Esqr Kirkaldy' are probably in Hume's hand, and the slip may well have been cut from the cover of the letter. The contents of the letter, to be sure, point definitely to Adam Smith as the recipient. For one thing, Hume stresses that the house he has in mind for his correspondent 'has a Prospect of... even I believe Kirkaldy,' and Smith was certainly the most prominent of Hume's intimate friends then living in 202 the 'lang toun' visible across the Firth of Forth from many parts of Edinburgh. There were others associated with Kirkcaldy, of course, such as James Oswald of Dunnikier, also Smith's childhood friend and someone with a great interest in political economy, but he had died in 1769. One might think, too, of the brothers Adam, in particular Robert and John, rising architects and later designers of Hume's memorial on Carlton Hill, but the focus of their life was London by this date, and they were unlikely to be asking Hume for an account of the money imported into Spain. In Hume's later years, he delighted in conversing with his friends in his home, and would call on them to pass time with him, even to move to Edinburgh to be near him. For example, he wrote to Smith on 23 November 1772 (corr. 134) that Adam Ferguson 'comes over next week, to a house in this neighbourhood. Pray, come over this winter, and join us.' On other occasions, too, he urged Smith to come to Edinburgh to visit him or to settle there so that they could enjoy each other's company. Thus, the first point suggesting that the new letter must be addressed to Smith arises from awareness of the relationship between Hume and Smith at this period. As is well known, Smith left the service of the Duke of Buccleuch in 1767 and returned from London to Kirkcaldy. There he lived with his mother and immersed himself in writing the Wealth of Nations until he left for London in May 1773 to see to the publication of his great book. As John Rae wrote of the intervening years: 'Hume, who thought the country an unsuitable place for a man of letters, used every endeavour to persuade [Smith] to remove to 2 Edinburgh, but without success.' 203 In a letter from James's Court of the Old Town, dated 20 August 1769 (Corr. 121), Hume asked Smith with all sincerity, ¦ but with a pleasing sense of humour, to spend some time with him: I am glad to have come within sight of you, and to have a View of Kirkaldy from my Windows: But as I wish also to be within speaking terms of you, I wish we coud concert measures for that purpose. I am mortally sick at Sea, and regard with horror, and a kind of... (shrink)

Illustrations: Numerous B/w Figures Description: Key questions in the history of Navya-nyaya (New Nyaya) remain unresolved: when did this school of logic begin, who was its founder, what distinguishes Navya-nyaya from Pracina-nyaya (Old Nyaya), and so on. This book attempts to answer these key questions in Part I. Part II provides a translation, analysis, and critical edition of the Lion and Tiger Definitions of Invariable Concomitance Chapter (Simha-vyaghra-laksana: LT Chapter) of the Tattva-cintamani-rahasya (TCR) of Mathuranatha (16th-17th c.). The hypothesis adopted (...) by the author with regard to the first question is that Udayana, who lived in the 11th century, is the founder of Navya-nyaya. This hypothesis is closely linked to the hypothesis offered regarding the second question, which is that the feature that distinguishes Navya-nyaya from the earlier school is its description of concepts and the structure of the world in terms of relation. Early Navya-nyaya authors, who flourished between Udayana and Gangesa (14th c.), devised specific terminology, of which delimitor (avacchedaka) and describer (niËpaka) are the most important, in order to identify or specify relation. This book attempts to illustrate the function of these and other Navya-nyaya terms from the viewpoint of relation. The main sources upon which the author has based his conclusions are Udayana s Laksanavali and the chapters on invariable concomitance or pervasion (vyapti) of the Nyaya-siddhanta-dipa (NSD) of Sasadhara (13rd-14th c.), the Tattva-cintamaÆi (TC) of Gangesa, and the TCR. Of these Sanskrit texts no scholar has worked on the Invariable Concomitance Chapter (Vyapti-vada) of the NSD in detail or the LT Chapter of the TCR. The latter chapter follows in the TCR the Five Definitions of Invariable Concomitance Chapter (Vyapti-pancaka), which Ingalls edited, translated, and analyzed in his epoch-making book Materials for the Study of Navya-Nyaya Logic (1951). One major innovation of this book made in Part II is to explain the structure of Navya-nyaya analysis by employing 86 diagrams based on the dharma-dharmin (property and property-possessor) relation, which serve as a visual aid and help readers to more easily understand the complicated structure of its analysis. The diagrams are also helpful in ascertaining how the definitions of invariable concomitance apply to individual cases and how the entities are connected in the application of the definitions. Another major innovation is: almost every sub-section of the LT Chapter of the TCR contains Mathuranatha s clarification of part of the two definitions; but this clarification does not give the definition incorporating prior clarifications and insertions; this book provides such a definition accompanied by a diagram. In other words, Part II illustrates the structure of the whole definition at every process of the clarification, which (definition) is never presented as such in Mathuranatha s text. (shrink)

Let f be a computable function from finite sequences of 0ʼs and 1ʼs to real numbers. We prove that strong f-randomness implies strong f-randomness relative to a PA-degree. We also prove: if X is strongly f-random and Turing reducible to Y where Y is Martin-Löf random relative to Z, then X is strongly f-random relative to Z. In addition, we prove analogous propagation results for other notions of partial randomness, including non-K-triviality and autocomplexity. We prove that f-randomness relative to a (...) PA-degree implies strong f-randomness, hence f-randomness does not imply f-randomness relative to a PA-degree. (shrink)

Every computable function has to be continuous. To develop computability theory of discontinuous functions, we study low levels of the arithmetical hierarchy of nonuniformly computable functions on Baire space. First, we classify nonuniformly computable functions on Baire space from the viewpoint of learning theory and piecewise computability. For instance, we show that mind-change-bounded learnability is equivalent to finite View the MathML source2-piecewise computability 2 denotes the difference of two View the MathML sourceΠ10 sets), error-bounded learnability is equivalent to finite View (...) the MathML sourceΔ20-piecewise computability, and learnability is equivalent to countable View the MathML sourceΠ10-piecewise computability . Second, we introduce disjunction-like operations such as the coproduct based on BHK-like interpretations, and then, we see that these operations induce Galois connections between the Medvedev degree structure and associated Medvedev/ Muchnik-like degree structures. Finally, we interpret these results in the context of the Weihrauch degrees and Wadge-like games. (shrink)

A system for analyzing concerns of people from Weblog articles is proposed. The system called KANSHIN analyzes concerns of people by collecting Japanese, Chinese, and Korean Weblog articles. Users can find concerns of people in each language. Users can also compare differences of concerns between Japanese, Chinese, and Korean language communities. We describe several analysis results: (1) patterns of social concerns, (2) change of focuses on a problem along with the time, (3) differences of concerns on a problem between Japanese, (...) Chinese, and Korean Weblog sites, and (4) relation between words in Weblog articles and real world natural phenomenon. (shrink)

It is known that infinitely many Medvedev degrees exist inside the Muchnik degree of any nontrivial Π10 subset of Cantor space. We shed light on the fine structures inside these Muchnik degrees related to learnability and piecewise computability. As for nonempty Π10 subsets of Cantor space, we show the existence of a finite-Δ20-piecewise degree containing infinitely many finite-2-piecewise degrees, and a finite-2-piecewise degree containing infinitely many finite-Δ20-piecewise degrees 2 denotes the difference of two Πn0 sets), whereas the greatest degrees in (...) these three “finite-Γ-piecewise” degree structures coincide. Moreover, as for nonempty Π10 subsets of Cantor space, we also show that every nonzero finite-2-piecewise degree includes infinitely many Medvedev degrees, every nonzero countable-Δ20-piecewise degree includes infinitely many finite-piecewise degrees, every nonzero finite-2-countable-Δ20-piecewise degree includes infinitely many countable-Δ20-piecewise degrees, and every nonzero Muchnik degree includes infinitely many finite-2-countable-Δ20-piecewise degrees. Indeed, we show that any nonzero Medvedev degree and nonzero countable-Δ20-piecewise degree of a nonempty Π10 subset of Cantor space have the strong anticupping properties. Finally, we obtain an elementary difference between the Medvedev degree structure and the finite-Γ-piecewise degree structure of all subsets of Baire space by showing that none of the finite-Γ-piecewise structures is Brouwerian, where Γ is any of the Wadge classes mentioned above.

Kierstead showed that every computable marriage problem has a computable matching under the assumption of computable expanding Hall condition and computable local finiteness for boys and girls. The strength of the marriage theorem reaches or if computable expanding Hall condition or computable local finiteness for girls is weakened. In contrast, the provability of the marriage theorem is maintained in even if local finiteness for boys is completely removed. Using these conditions, we classify the strength of variants of marriage theorems in (...) the context of reverse mathematics. Furthermore, we introduce another condition that also makes the marriage theorem provable in, and investigate the sequential and Weihrauch strength of marriage theorems under that condition.

Probably very few people today would believe that, prior to Japan's modernization during the Meiji period, the Japanese were not able to run. It seems commonsensical that human beings should be able to perform the same body movements such as running—since, of course, we are human beings regardless of whether we live in modern countries. However, it appears, in fact, that people in the Edo Period did not run in the sense of how we run today. There was no need, (...) for example, for farmers to run in the midst of their daily agricultural activities.In addition, it has been also pointed out that, although some premodern Japanese, such as samurai or official messengers...

To compare two randomness notions with each other, we ask whether a given randomness notion can be defined via another randomness notion. Inspired by Yu's pioneering study, we formalize our question using the concept of relativization of randomness. We give some solutions to our formalized questions. Also, our results include the affirmative answer to the problem asked by Yu in a discussion with the second author, i.e., whether Schnorr randomness relative to the halting problem is equivalent to Martin‐Löf randomness relative (...) to all low 1‐generic reals.

The number of competing-brands changes by new product's entry. The new product introduction is endemic among consumer packaged goods firm and is an integral component of their marketing strategy. As a new product's entry affects markets, there is a pressing need to develop market response model that can adapt to such changes. In this paper, we develop a dynamic model that capture the underlying evolution of the buying behavior associated with the new product. This extends an application of a dynamic (...) linear model, which is used by a number of time series analyses, by allowing the observed dimension to change at some point in time. Our model copes with a problem that dynamic environments entail: changes in parameter over time and changes in the observed dimension. We formulate the model with framework of a state space model. We realize an estimation of the model using modified Kalman filter/fixed interval smoother. We find that new product's entry (1) decreases brand differentiation for existing brands, as indicated by decreasing difference between cross-price elasticities; (2) decreases commodity power for existing brands, as indicated by decreasing trend; and (3) decreases the effect of discount for existing brands, as indicated by a decrease in the magnitude of own-brand price elasticities. The proposed framework is directly applicable to other fields in which the observed dimension might be change, such as economic, bioinformatics, and so forth. (shrink)
