Dear all,
I am writing a code using Python now.
I want to know how to find out values of all feasible x under constraints.
x = [x_1, x_2, x_3,..., x_10]
constraints:
x_i = 0,1,2,3 or 4, where i=1,2,....10
x_1 + x_2 + x_3 +...+x_10 <= 15
How to find out all the feasible solutions x (domain of x) using python, like
[0,0,0,0,0,0,0,0,0,0], [1,1,1,1,1,1,1,1,1,1] etc ? What should be the code?
Any hint or help would be highly appreciated!
Sincerely,
Xiang Zhang
There are several constraint libraries on pypi if you don't want to roll
your own. See for example
