Abstract

The slater voting rule is a tournament-based voting rule. It mainly constructs a ringless tournament, finds the one with the smallest difference from the original tournament, and selects the winner from it. Aiming at the NP-hard slater voting algorithm, this paper proposed a Picat method to solve the slater problem based on the optimization of similar candidate item sets. Compared with the non-optimized Picat method for solving the slater problem, this method reduced the solution space of the slater algorithm, effectively reduced the amount of calculation for solving the slater winner, and improved the calculation speed. The experimental results show that the computational speed of the optimized Picat method for solving the slater problem is better than that of the non-optimized. When the number of candidates is less than 20, the computational speed and computing power of the answer set program(ASP) method for solving the slater problem are better than those of the optimized Picat method, but when the number of candidates exceeds 30, the optimized Picat method(with a satisfiable problem solver) outperforms the ASP method in terms of computational speed and computational power.
