Detailed Description

Dummy class that define required methods for a solver of a scheduling instance.

This class defines the required methods to be implemented by a class that is able to solve a scheduling instance.

Constructor & Destructor Documentation

delphos::FractionalScheduler::FractionalScheduler

(

delphos::SchedulingInstance &

si

)

Creates a new scheduler.

Parameters

si	The scheduling instance to be solved.

Member Function Documentation

const double delphos::FractionalScheduler::GetDual ( const string &  cname )

virtual

Return the dual value of given constraint.

Parameters

cname

The name of the constraint of which the dual value is returned. This implementation is a dummy version that always returns 0.

Reimplemented in delphos::GurobiFractionalScheduler, and delphos::CBCFractionalScheduler.

bool delphos::FractionalScheduler::Run ( )

virtual

Solves the scheduling instance. Returns true on success.

In this class, it is simply a dummy method that returns always false.

Reimplemented in delphos::BZ, delphos::CBCFractionalScheduler, delphos::GurobiFractionalScheduler, delphos::GurobiBZ, and delphos::CBCBZ.

void delphos::FractionalScheduler::SetLogFile ( const string &  name )

virtual

Set the use of the log with given file name.

Parameters

name	The name of the log file. This implementation is a dummy version that do nothing.

Reimplemented in delphos::CBCFractionalScheduler, delphos::BZ, and delphos::GurobiFractionalScheduler.

void delphos::FractionalScheduler::SetLPMethod

(

const int &

lpcode

)

Set LP method.

Parameters

lpcode

The code of lp method(simplex,dual simplex,barrier,...)
