Constructor Detail

ACGJ3FixedValue

public ACGJ3FixedValue(Infrastructure _i)

Creates a new ACGJ3 Algorithm. This TLC-algorithm is using genetic techniques to find an optimum in calculating the gains for each trafficlight. Till date it hasnt functioned that well. Rather poorly, to just say it.

Parameters:

_i - The infrastructure this algorithm will have to operate on

Method Detail

setInfrastructure

public void setInfrastructure(Infrastructure _i)

Changes the Infrastructure this algorithm is working on

Overrides:

setInfrastructure in class TLController

Parameters:

_i - The new infrastructure for which the algorithm has to be set up

decideTLs

public TLDecision[][] decideTLs()

Calculates how every traffic light should be switched

Specified by:

decideTLs in class TLController

Returns:

Returns a double array of TLDecision's. These are tuples of a TrafficLight and the gain-value of when it's set to green.

See Also:

gld.algo.tlc.TLDecision

reset

public void reset()

Resets the algorithm

Overrides:

reset in class TLController

updateRoaduserMove

public void updateRoaduserMove(Roaduser _ru,
                               Drivelane _prevlane,
                               Sign _prevsign,
                               int _prevpos,
                               Drivelane _dlanenow,
                               Sign _signnow,
                               int _posnow,
                               PosMov[] posMovs,
                               Drivelane _desired)

Provides the TLC-algorithm with information about a roaduser that has had it's go in the moveAllRoaduser-cycle. From this information it can be distilled whether a roaduser has moved or had to wait.

Specified by:

updateRoaduserMove in class TLController

Parameters:

_ru -

_prevlane -

_prevsign -

_prevpos -

_dlanenow -

_signnow -

_posnow -

posMovs -

_desired -
