This paper describes a Competitive Co-evolutionary Algorithm with electric charge model to solve Tsumego. The following three procedures achieve an effective evolutionary process. 1- The Go stones used in Tsumego are assumed to be electric charges. 2- In any specific arrangement of Go stones on the board in Tsumego, the electrical potential distribution of each intersection (where a stone is placed) on the board has a specific calculation. 3- Based on the electrical potential distribution (or variation of electric potential), intersections that do not reach a specific threshold level are excluded. (Intersections on the board are considered to...
