Detailed Description

A master for parallel system solving TSP problem.

[Inherited]

Master is an abstract and example class, for providing guidance of realizing parallel processing system for users, within framework of master. The Master class represents a master of parallel processing system in the master side.

A master system (represented by Master and MasterDriver) is associated with a chief system (represented by Cheif and CheifDriver) and slave systems (Slave and SlaveDriver). The master system gets optimization order from chief system and shifts and distributes orders to its slave systems. When slave systems report optimization result, the master system aggregates those results and reports the aggregated results to chief system.

Constructor & Destructor Documentation

samchon::example::interaction::TSPMaster::TSPMaster ( )

inline

Default Constructor.

Definition at line 46 of file TSPMaster.hpp.

Member Function Documentation

virtual void samchon::example::interaction::TSPMaster::optimize ( shared_ptr< XML > xml )

inlineoverrideprotectedvirtual

Optimize something.

Master gets an XML object representing parametric value and basic data used for optimzation are came from Cheif. Master constructs some object to optimize and distributes the optimization order to master's slave systems by segmentation.

Parameters

xml	XML object representing parametric value and basic data used for optimization.

Reimplemented from samchon::example::interaction::Master.

Definition at line 57 of file TSPMaster.hpp.

virtual void samchon::example::interaction::TSPMaster::replyOptimization ( shared_ptr< XML > xml )

inlineoverrideprotectedvirtual

Handle (replied) optimized value from a slave system.

When gets optimization result from Slave systems, Master aggregates them and derives the best solution between those results and reports the best solution to the Cheif system.

Parameters
