ECOS-class: The ECOS class.

Description

This class is an interface for the ECOS solver.

Usage

lp_capable(solver)
# S4 method for ECOS
socp_capable(solver)
# S4 method for ECOS
sdp_capable(solver)
# S4 method for ECOS
exp_capable(solver)
# S4 method for ECOS
mip_capable(solver)
# S4 method for ECOS
name(object)
# S4 method for ECOS
import_solver(solver)
# S4 method for ECOS
Solver.solve(solver, objective, constraints, cached_data,
  warm_start, verbose, ...)
# S4 method for ECOS
format_results(solver, results_dict, data, cached_data)

Arguments

object, solver

An '>ECOS object.

objective

A list representing the canonicalized objective.

constraints

A list of canonicalized constraints.

cached_data

A list mapping solver name to cached problem data.

warm_start

A logical value indicating whether the previous solver result should be used to warm start.

verbose

A logical value indicating whether to print solver output.

...

Additional arguments to the solver.

results_dict

A list containing the solver output.

data

A list containing information about the problem.

Methods (by generic)

lp_capable: ECOS can handle linear programs.
socp_capable: ECOS can handle second-order cone programs.
sdp_capable: ECOS cannot handle semidefinite programs.
exp_capable: ECOS can handle exponential cone programs.
mip_capable: ECOS cannot handle mixed-integer programs.
name: The name of the solver.
import_solver: Imports the ECOSolveR library.
Solver.solve: Call the solver on the canonicalized problem.
format_results: Convert raw solver output into standard list of results.
