Constructor Details

CloudletToVmMappingSimulatedAnnealing

public CloudletToVmMappingSimulatedAnnealing(double initialTemperature,
 ContinuousDistribution random)

Creates a Simulated Annealing Heuristic for solving Cloudlets to VMs mapping.

Parameters:

initialTemperature - the system initial temperature

random - a pseudo-random number generator

Method Details

getInitialSolution

public CloudletToVmMappingSolution getInitialSolution()

Description copied from interface: Heuristic

Gets the initial solution that the heuristic will start from to try to improve it. If no initial solution was generated yet, one should be randomly generated.

Specified by:

getInitialSolution in interface Heuristic<CloudletToVmMappingSolution>

Returns:

the initial randomly generated solution

createNeighbor

public CloudletToVmMappingSolution createNeighbor(CloudletToVmMappingSolution source)

Description copied from interface: Heuristic

Creates a neighbor-solution cloning a source one and randomly changing some of its values. A neighbor solution is one that is close to the current solution and has just small changes.

Specified by:

createNeighbor in interface Heuristic<CloudletToVmMappingSolution>

Parameters:

source - the source to create a neighbor solution

Returns:

the cloned and randomly changed solution that represents a neighbor solution
