A solution search system, which can search for a test object, expected to output an optimal result, from at least two test objects each outputting a result based on a probability distribution, includes: a record superiority comparing unit which can obtain past records of the test objects based on an accumulation of the output results and can compare all records for superiority/inferiority; a controlling unit which can control a measurement variable of the test objects, based on the compared superiority/inferiority records, and a latest result output from the test object; and an output instructing unit which can instruct the test object, the measurement variable of which has exceeded a threshold value, to output a result, wherein the output instructing unit determines, as a desired solution, at least one test object to which the largest number of the output instructions have finally been given after repetition of the output instructions.

Solution search for combinatorial bandit problem

There are provided a quantum dot, a plurality of quantum dots having a larger volume than the quantum dot, a light detection unit for detecting a light emission state of an output light from the plurality of quantum dots, and a light supply unit capable of supplying a control light to the plurality of quantum dots thereby to excite other exciters to a lower level, and controlling energy discharging of the exciters transiting to the lower level, wherein the control light to be supplied by the light supply unit is controlled per quantum dot based on the light emission state of the output light per quantum dot and previously-input search problem information.
