I'd like to standardize a few cvxpy problems and use them in many places in my codebase. Here is a cleaned example:
from cvxpy import Variable, Parameter, Problem, Minimize
def problem_builder(n, ...)
var = Variable(n)
param = Parameter(n)
costs = #Some complex convex function of var and param
return Problem(Minimize(costs), constraints)
prob = problem_builder(4)
prob.var.value = [1,2,3,4] #???
prob.parameters()[0] = [1,2,3,4] #Ugly ???
I could create var and param outside the function and then pass them around with the problem but that seems awkward.
Can I access var and param somehow from prob? What are the best practices around using the same cvxpy Problem across multiple modules?
You can now access the parameters and variables as a dictionary using:
param = cp.Parameter(name='paramname')
problem.param_dict
and
var = cp.Variable(name='varname')
problem.var_dict
where the parameter/variable names are the keys of the dictionary
