ECOS_BB-class: The ECOS_BB class.

Description

This class is an interface for the ECOS BB (branch-and-bound) solver.

Usage

ECOS_BB()
# S4 method for ECOS_BB
lp_capable(solver)
# S4 method for ECOS_BB
socp_capable(solver)
# S4 method for ECOS_BB
sdp_capable(solver)
# S4 method for ECOS_BB
exp_capable(solver)
# S4 method for ECOS_BB
mip_capable(solver)
# S4 method for ECOS_BB
name(object)
# S4 method for ECOS_BB
Solver.solve(solver, objective, constraints,
  cached_data, warm_start, verbose, ...)

Arguments

object, solver

A '>ECOS_BB 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.

Methods (by generic)

lp_capable: ECOS_BB can handle linear programs.
socp_capable: ECOS_BB can handle second-order cone programs.
sdp_capable: ECOS_BB cannot handle semidefinite programs.
exp_capable: ECOS_BB cannot handle exponential cone programs.
mip_capable: ECOS_BB can handle mixed-integer programs.
name: The name of the solver.
Solver.solve: Call the solver on the canonicalized problem.
