A Derivation A = > Derivation Tree Derivation A = > Derivation Tree
The basic Schema Theorem for genetic algorithms is modiied for a grammatically-based learning system. A context-free grammar is used to deene a language in which each sentence is mapped to a tness value. The derivation trees associated with these sentences are used to deene the structure of schemata. The eeect of crossover and mutation on schemata is described. A schema theorem is developed whi...
متن کاملJordan derivation on trivial extension
Let A be a unital R-algebra and M be a unital A-bimodule. It is shown that every Jordan derivation of the trivial extension of A by M, under some conditions, is the sum of a derivation and an antiderivation.
متن کاملTransfers and Development Easy Come , Easy Go ?
A central behavioral assumption of economic theory is that income is fungible. Yet, building on the pioneering work by Thaler (1999) recent work by behavioural economists highlights that people code income in different mental accounts, creating a direct link between spending behaviour and income sources, thereby violating the fungibility assumption. This paper examines whether the marginal prop...
متن کاملEasy Sets Without Easy Small Subsets
We show the existence of relativized worlds relative to which there exist innnite polynomial-time computable sets without innnite polynomial-time computable sparse subsets or even non-deterministically polynomial-time computable sparse subsets. This result is tight since every innnite P set has an innnite sparse coNP subset.
متن کاملEasy Come - Easy Go Divisible Cash
Recently, there has been an interest in creating practical anonymous electronic cash with the ability to conduct payments of exact amounts, as is typically the practice in physical payment systems. The most general solution for such payments is to allow electronic coins to be divisible (e.g., each coin can be spent incrementally but total purchases are limited to the monetary value of the coin)...
