Base Claim:
1. An information processing apparatus comprising: an algorithm configuring section that configures an amount-of-feature extraction algorithm that determines whether an input signal has a particular characteristic by using a genetic search technique, the algorithm comprising: feature extraction expressions that specify: a type of the input signal, the type indicating a type of data representing the input signal; and operations to be performed on the input signal; and an information estimation expression including a linear combination of the feature extraction expressions, wherein the information estimation expression uses first-order values output from the feature extraction expressions to estimate information indicating features of the input signal; a tradeoff analyzing section that generates pareto optimal solutions by selecting information estimation expressions having maximum values of evaluation indices; an optimum algorithm determining section that selects, from the pareto optimal solutions, an optimum algorithm that matches a requested condition of the evaluation indices; and a storage for storing the algorithm.

Claim 3:
3. The information processing apparatus according to claim 1 , wherein the tradeoff analyzing section generates pareto optimal solutions in an initial state by using algorithms having different numbers of feature extraction expressions, the algorithms being created by deleting the feature extraction expressions one by one from the algorithm configured by the algorithm configuring section.
