来自LINGO软件的Playtpus改编

如何解决来自LINGO软件的Playtpus改编

我正在尝试将我的问题从LINGO软件改编为Playtpus语言，但我无法运行此代码。有人可以告诉我哪里出了问题吗？代码是：

#variaveis

M_massamolar = 32*0.000001;
B_massamolar = 292*0.000001;
G_massamolar = 92*0.000001;

S_capacidade = 3600000;
OR_capacidade = 367200;
B_capacidade = 887760*(880/1000);

S_demanda = 80638;
F_demanda = 398984;
OB_demanda = 164700;
OR_demanda = 164700;
B_demanda = 77634;

problem = Problem(13,2,18)

problem.constraints[16] = ">=0"
problem.constraints[17] = ">=0"
problem.function = belegundu

algorithm = NSGAII(problem)
algorithm.run(10000000)

问题是：

    190         else:
    191             objs = self.function(solution.variables)

ValueError：没有足够的值可解包（预期2，得到1）

我不明白自己做错了什么。有人可以帮助我吗？有人知道Python库中的Playtpus工具吗？
