Abstract: A simulated annealing device includes a solving unit which solves a SAT (Boolean Satisfiability Testing) expressed in a CNF (Conjunctive Normal Form) form with constraint information indicating one or more constraints imposed on a combinatorial optimization problem converted, to obtain sets of values of multiple variables of the combinatorial optimization problem that satisfy the one or more constraints, which are candidate solutions to the combinatorial optimization problem.

Abstract: The conversion means 72 generates a program for deriving a QUBO matrix that is a matrix that defines an energy function of QUBO, by converting a description of a natural language representing a combinatorial optimization problem into a description of the program for deriving the QUBO matrix. It is possible to generate a program for deriving a QUBO matrix based on a description of a natural language representing a combinatorial optimization problem.

Abstract: An information processing device includes: a feature quantity obtaining unit which obtains a feature quantity of an object to be extracted, which is extracted from a retrieval target, and specific information to be specified an appearing location of it; a feature quantity holding unit which, when storing the feature quantity in a feature quantity table, adds new identification information to the feature quantity and holds the feature quantity in the feature quantity table when a similar feature quantity in which a similarity with the feature quantity is no less than a threshold is not included in the feature quantity table, and outputs identification information of the similar feature quantity as identification information of the feature quantity when the similar feature quantity is included in the feature quantity table; and a retrieval table holding unit which holds the specific information associated with the added identification information or the outputted identification information.

Abstract: By solving SAT expressed in a form of CNF in which constraints other than a no-transformation constraint, which is a constraint that satisfies a prescribed condition among one or more constraints imposed on a combinatorial optimization problem, are transformed, so that the no-transformation constraint is satisfied, a solution unit obtains a combination of values of multiple variables of the combinatorial optimization problem, wherein the combination is a candidate of solution of the combinatorial optimization problem and satisfies the one or more constraints.

Abstract: The difference matrix calculation means 72 calculates a difference matrix which is a difference between a first matrix representing a combinatorial optimization problem for which a solution was found last time and a second matrix representing the latest combinatorial optimization problem. The difference matrix compression means 73 compresses the difference matrix. The transmission means 74 transmits the difference matrix after compression to a combinatorial optimization problem solution device that finds a solution to the combinatorial optimization problem.
