Arguments

• object: A SolvingChain object.
• chain: A Chain to prepend.
• problem: The problem to solve.
• warm_start: A boolean of whether to warm start the solver.
• verbose: A boolean of whether to enable solver verbosity.
• feastol: The feasible tolerance.
• reltol: The relative tolerance.
• abstol: The absolute tolerance.
• num_iter: The maximum number of iterations.
• solver_opts: A list of Solver specific options
• data: Data for the solver.

Methods (by generic)

• prepend(object = SolvingChain, chain = Chain): Create and return a new SolvingChain by concatenating chain with this instance.
• reduction_solve(object = SolvingChain, problem = Problem): Applies each reduction in the chain to the problem, solves it, and then inverts the chain to return a solution of the supplied problem.
• reduction_solve_via_data(SolvingChain): Solves the problem using the data output by the an apply invocation.
