problem_unpack_results: Unpack Solver Results into a Problem

In CVXR: Disciplined Convex Optimization

Unpack Solver Results into a Problem

Description

Inverts the reduction chain and unpacks the raw solver solution into the original problem's variables and constraints. This is step 3 of the decomposed solve pipeline:

1. problem_data() – compile the problem

2. solve_via_data(chain, data) – call the solver

3. problem_unpack_results() – invert and unpack

Usage

problem_unpack_results(problem, solution, chain, inverse_data)

Arguments

problem	A Problem object.
solution	The raw solver result from solve_via_data().
chain	The SolvingChain from problem_data().
inverse_data	The inverse data list from problem_data().

Details

After calling this function, variable values are available via value() and constraint duals via dual_value().

Value

The problem object (invisibly), with solution unpacked.
