The epistemic virtues, as identified by virtue epistemology virtue epistemologists , reflect their contention that belief is an ethical process, and thus susceptible to the intellectual virtue or vice of one s own life and personal experiences.

Walter M. Fitch May 21, 1929 March 10, 2011 was professor of molecular evolution at the University of California, Irvine , until his death. He was also a member of the United States National Academy of Sciences National Academy of Sciences , the American Philosophical Society , and the American Association for the Advancement of Science , and was a Foreign Member of the Linnean Society of London Linnean Society London . He is the co founder of the journal Molecular Biology and Evolution , together with Masatoshi Nei , and was the first president of the Society for Molecular Biology and Evolution . Walter Fitch is noted for his pioneering work on reconstruction of Phylogenetic tree phylogenies evolutionary trees from protein and DNA sequences. Among his achievements are the first major paper on distance matrix methods, which introduced the Fitch Margoliash method which seeks the tree that best predicts a set of pairwise distances among species. He also developed the Fitch parsimony algorithm, which evaluates rapidly and exactly the minimum number of changes of state of a sequence on a given phylogeny. His definition of Homology 28biology 29 Orthology orthologous sequences has been very often cited and used as a reference in many research publications. Major papers Fitch, W. M. and E.

ECJ is a freeware evolutionary computation research system written in Java. It is a framework that supports a variety of evolutionary computation techniques, such as genetic algorithms , genetic programming , evolution strategies , coevolution , particle swarm optimization, and differential evolution. The framework models iterative evolutionary processes using a series of pipelines arranged to connect one or more subpopulations of individuals with Selection genetic algorithm selection , breeding such as Crossover genetic algorithm crossover , and Mutation genetic algorithm mutation operators that produce new individuals. The framework is open source and is distributed under the Academic Free License .

No footnotes date April 2011 Overengineering or over engineering is when a product is more robust or complicated than necessary for its application, either charitably to ensure sufficient factor of safety , sufficient functionality, or due to design errors. Overengineering is desirable when safety or performance on a particular criterion is critical, or when extremely broad functionality is required, but it is generally criticized from the point of view of value engineering as wasteful. As a design philosophy , such overcomplexity is the opposite of the Minimalism Minimalist design less is more school of thought and hence a violation of the KISS principle and parsimony . Overengineering generally occurs in high end products or specialized market criteria, and takes various forms. In one form, products are overbuilt, and have performance far in excess of needs a family sedan that can drive at 300  km h, or a home video cassette recorder with a projected lifespan of 100 years , and hence are more expensive, bulkier, and heavier than necessary. Alternatively, they may be overcomplicated the design may be far more complicated than is necessary for its use, such as a modern text editor asking whether files should be saved in ASCII or EBCDIC format. Overcomplexity reduces usability of the product by the end user , and can decrease productivity of the design team due to the need to build and maintain all the features. A related issue is market segmentation making different products for different market segments. In this context, a particular product may be more or less suited for a particular market segment, and may be over or under engineered relative to an application. German tanks in World War II Second World War German tanks are typical examples of overengineered vehicles, which made them more expensive, fewer in number, more difficult to produce and heavier than their Soviet and Allied counterparts.

The film stars Aftab Shivdasani and Ameesha Patel in lead roles. Kader Khan , Gulshan Grover and Asrani made supporting roles in the film. Synopsis Mr. Raj K. Saxena Kader Khan is known for his parsimony. Everything he does and thinks is valued with money, and ways he can accumulate it. His daughter, Kiran Ameesha Patel , is the opposite, a spendthrift. Mr. Saxena borrows money from elderly people, assuring them of returning the loan with a handsome rate of interest after about 20 years, knowing fully well that none of them will survive 20 years. Then he meets with the son of one of such lender, aptly named after him viz. Raj K. Saxena Aftab Shivdasani Aftab . Mr. Saxena refuses to repay the amount, swallows the proof, the only evidence, and asks Raj to get out, which he does so. Raj is determined to get his money, and wants Kiran to fall in love with him. Kiran does so, and brings him over to introduce him to her shocked and speechless dad. Things change when Raj inherits a large amount of money, ironically left by Mr. Saxena maternal grandmother, and it is Mr. Saxena who is now anxious to get in the good books of Raj, with hilarious results.
