如何在ORTOOLS for MILP中使用SCIP [python]

from ortools.linear_solver import pywraplp

def main():
    # 创建SCIP求解器
    solver = pywraplp.Solver.CreateSolver('SCIP')

    # 定义变量、约束和目标函数
    x = solver.IntVar(0, 1, 'x')
    y = solver.IntVar(0, 2, 'y')
    constraint = solver.Constraint(0, 2, 'constraint')
    constraint.SetCoefficient(x, 1)
    constraint.SetCoefficient(y, 1)
    objective = solver.Objective()
    objective.SetCoefficient(x, 1)
    objective.SetCoefficient(y, 2)
    objective.SetMaximization()

    # 求解优化问题
    solver.Solve()

    # 输出结果
    print('Solution:')
    print('x = ', x.solution_value())
    print('y = ', y.solution_value())

if __name__ == '__main__':
    main()
