SolvingChain-class: The SolvingChain class.

In CVXR: Disciplined Convex Optimization

The SolvingChain class.

Description

This class represents a reduction chain that ends with a solver.

Usage

## S4 method for signature 'SolvingChain,Chain'
prepend(object, chain)

## S4 method for signature 'SolvingChain,Problem'
reduction_solve(
  object,
  problem,
  warm_start,
  verbose,
  feastol,
  reltol,
  abstol,
  num_iter,
  solver_opts
)

## S4 method for signature 'SolvingChain'
reduction_solve_via_data(
  object,
  problem,
  data,
  warm_start,
  verbose,
  feastol,
  reltol,
  abstol,
  num_iter,
  solver_opts
)

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.
