我正在尝试在Mac上使用PuLP来解决一个移动I问题。prob.solve(CPLEX_CMD()),File "/Users/xxxx/opt/anaconda3/envs/pulposm/lib/python3.7/site-packages/pulp/solvers.py", line 468, in actualSolve
raise PulpSolverError("Pu
我尝试用PuLP (objective的一部分)模拟下面的数学语句: ? 了解常见的表示法,如 pulp.lpSum(p.loc[t][tau]*d[t+tau]*q[t][tau] for t in T for tau in F) 我不确定如何包含tau小于或等于T - tau我以前使用过XPRESS,在那里我可以做一些事情,比如 forall(t in T, tau in F | tau<=T-t) 现在我的问题是,这是否也适用于PuLP? 提前谢谢。
我尝试在运行Anaconda3的PyCharm中运行下面提到的代码x = LpVariable("x", 0, 3)
y = LpVariable("y", 0,prob.solve(GLPK(msg = 0))文件"C:\Users\rahul.bajaj\AppData\Local\Continuum\Anaconda3\lib\site-packages\pulp\pulp.py",行1643,in solve status = sol
我只是安装了pulp,并按照这里的说明操作:https://www.coin-or.org/PuLP/main/installing_pulp_at_home.html#testing-your-pulp-installation但是,它会显示以下消息: AttributeError: module 'pulp' has no attribute 'pulpTestAll' 除此之外,glpk也不能安装: (base

我正在使用Python2.7,并使用PuLP库来设置一个问题。一旦定义了变量、目标和约束,我就会选择LpProblem对象以发送到别处的求解器。在取消我的问题时,我注意到所有的变量都是重复的:import pickle
x = pulp.LpVariable('x', 0, 10)
y = pulp.LpVari
我想要这样的东西: a = pulp.lpSum(...)c = pulp.lpSum(...)prob += a + b - c 我的代码更加具体: alloc_prob = pulp.LpProblem("Supplier Allocation Problem", pulp.LpMinimize)
TPC_func = pulp.lpSum(X[s][p]*procCosts[s][p] for s in
