You can use arithmetic operators:您可以使用算术运算符:
model.Add(4 * r + 2 * p == 56);
or或者
model.Add(LinearExpr.Sum(new IntVar[] {r, p}) == 20);
See: https://github.com/google/or-tools/blob/master/ortools/sat/doc/integer_arithmetic.md请参阅: https://github.com/google/or-tools/blob/master/ortools/sat/doc/integer_arithmetic.md
You can follow the examples in this section:您可以按照本节中的示例进行操作:
