Что я могу сделать для исправления ошибок в следующей программе
item= record( int: id, profit, weight);
set of item: All_Items ;
int :Max_Capacity;
var set of item: Selected_Items;
У меня есть следующий код для решения ранца в MiniZinc, но в нем много ошибок.
constraint sum([holds(X in Selected_Items)*X.weight | X in All_Items])=< Max_Capacity;
constraint Selected_Items >= All_Items;
maximize
sum([holds(S in Selected_Items)*S.profit |S in All_Items]);
