研究了在求解组合优化问题的伊辛机中二进制-整数编码的性能差异。许多组合优化问题可以映射到找到伊辛模型或其等价模型的最低能量(基态),二次无约束二元优化(QUBO)。由于伊辛模型和QUBO由二进制变量组成,因此在使用伊辛机时,它们通常将整数表示为二进制。一个典型的例子是不等式约束下的组合优化问题。在这里,二次背包问题被采用作为一个典型的问题与不等式约束。它使用典型的二进制-整数编码来解决:独热编码,二进制编码和一元编码。一元编码对于大型问题表现出最佳性能。
The differences in performance among binary-integer encodings in an Ising machine, which can solve combinatorial optimization problems, are investigated. Many combinatorial optimization problems can be mapped to find the lowest-energy (ground) state of an Ising model or its equivalent model, the Quadratic Unconstrained Binary Optimization (QUBO). Since the Ising model and QUBO consist of binary variables, they often express integers as binary when using Ising machines. A typical example is the combinatorial optimization problem under inequality constraints. Here, the quadratic knapsack problem is adopted as a prototypical problem with an inequality constraint. It is solved using typical binary-integer encodings: one-hot encoding, binary encoding, and unary encoding. Unary encoding shows the best performance for large-sized problems.
