An information processing apparatus for configuring algorithms is disclosed. The information processing apparatus includes an algorithm configuring section that configures an algorithm for performing discrimination on an input signal by using a genetic search technique. The algorithm includes feature extraction expressions and an information estimation expression represented by a combination of the feature extraction expressions. The information processing apparatus also includes a tradeoff analyzing section that determines pareto optimal solutions by optimizing the algorithm with respect to evaluation indices by performing tradeoff analysis on the basis of the algorithm. In addition, the information processing apparatus includes a storage for storing the algorithm.
