Abstract

An information processing apparatus to create an arithmetic expression by combining one or more operators includes a detection unit to detect a permutation of plural operators existing in common to the plural created arithmetic expressions, and a registration unit to register the detected permutation of the operators as a new operator.

Claims

1. An information processing apparatus to create an arithmetic expression by combining one or more operators, comprising:

detection means for detecting a permutation of plural operators existing in common to the plural created arithmetic expressions; and

registration means for registering the detected permutation of the operators as a new operator.

2. The information processing apparatus according to claim 1, wherein the detection means detects the permutation of the plural operators including at least one of a processing symmetry axis and a parameter.

3. The information processing apparatus according to claim 1, wherein the detection means creates plural permutations each including a specified number of operators, and detects one of the created permutations, which has a high appearance frequency in the plural arithmetic expressions.

4. The information processing apparatus according to claim 1, further comprising creation means for creating the arithmetic expression by combining one or more operators including the operator newly registered by the registration means.

5. An information processing method of an information processing apparatus to create an arithmetic expression including one or more operators, comprising the steps of:

detecting a permutation of plural operators existing in common to the plural created arithmetic expressions; and

registering the detected permutation of the operators as a new operator.

6. A program to create an arithmetic expression including one or more operators, the program causing a computer to execute a process comprising the steps of:

detecting a permutation of plural operators existing in common to the plural created arithmetic expressions; and

registering the detected permutation of the operators as a new operator.

7. An information processing apparatus to create an arithmetic expression by combining one or more operators, comprising:

a detecting section detecting a permutation of plural operators existing in common to the plural created arithmetic expressions; and

a registering section registering the detected permutation of the operators as a new operator.
