How do I set starting guess for dual variable in cvxpy? for a normal single value problem the solution is
x.value = 1/2
How would this be done for a dual variable problem?
Code example
import cvxpy as cp
# Create two scalar optimization variables.
x = cp.Variable()
y = cp.Variable()
# Create two constraints.
constraints = [x + y == 1,
x - y >= 1]
# Form objective.
obj = cp.Minimize((x - y)**2)
# Form and solve problem.
prob = cp.Problem(obj, constraints)
# This is the way I amagine but it does not work
constraints[0].dual_value = 3
prob.solve()
# The optimal dual variable (Lagrange multiplier) for
# a constraint is stored in constraint.dual_value.
print("optimal (x + y == 1) dual variable", constraints[0].dual_value)
print("optimal (x - y >= 1) dual variable", constraints[1].dual_value)
print("x - y value:", (x - y).value)
CVXPY does not currently support starting guesses, neither for primal or dual variables.
