Parameters ---------- problem : Problem The problem for which to build a chain. candidates : dict Dictionary of candidate solvers divided in qp_solvers and conic_solvers. gp : bool If True, the problem is parsed as a Disciplined Geometric Program instead of as a Disciplined Convex Program. Returns ------- Chain A Chain that can be used to convert the problem to an intermediate form. Raises ------ DCPError Raised if the problem is not DCP and `gp` is False. DGPError Raised if the problem is not DGP and `gp` is True. r) reductionsDCPzU However, the problem does follow DGP rules.
