在PuLP中打印三维变量的索引以进行调度

from pulp import *

prob = LpProblem("Scheduling Problem", LpMinimize)
x = LpVariable.dicts("x", (range(3), range(4), range(5)), cat='Binary')

# 添加约束条件
prob += lpSum(x[i][j][k] for i in range(3) for j in range(4) for k in range(5)) == 1

# 添加目标函数
prob += lpSum(x[i][j][k] * (i + j + k) for i in range(3) for j in range(4) for k in range(5))

# 解决问题
prob.solve()

# 打印索引
for v in prob.variables():
    if v.varValue == 1:
        print(v.name)
