Detailed Description

In this class we are dealing with those aspects of the game that can be loosely called the environment. The environment or world will be responsible for the results of the choices. Whether an invitation or an idea is successfull, what qualities they will have etc..

The only action that is independent of the environment is leisure which always results in a direct reward. For the other actions this class will provide these attributes:

NEWIDEA Quality distributed gaussian (truncated according) to DA Ruwe.
IMPROVEQuality distribution.
IMPROVESuccess distribution.
INVITEDistirbution of resulting players

Member Function Documentation

void ideation.Environment.happens	(	Period	period,
		Game	game
	)

Should only be called once in each period and that after the agents have made their choices, i.e. after ideation.Agent#play(Period).

Parameters:

period	the period ion which these events are to take place.
game	the game in which we are playing.

static double ideation.Environment.probability_idea ( double qBest ) [static]

Parameters:

qBest quality to be bested

Returns:: probability of achieving a better result with new idea.

static double ideation.Environment.quality_improve ( double prevIdeaValue ) [static]

This is a function of its own, so that it can be accessed by anyone who needs it outside. Thereby if we want to change this function we only have to do so here.

The points in the code are neccessary because of javas handling of division for integers!

Parameters:

prevIdeaValue The quality of the idea that is to be improved.

Returns:: The quality of the new idea.

static double ideation.Environment.result_idea ( ) [static]

Returns:: The quality of the new idea.

static double ideation.Environment.result_improve ( double prevIdeaValue ) [static]

Parameters:

prevIdeaValue The quality of the idea that is to be improved.

Returns:

0 if the idea was not successful.
the quality of the created improvement if the idea was successful.

static computerPlayer ideation.Environment.result_randomInvite ( ) [static]

If the action of invitation is picked, multiple computer players get invited. This function calculates the probabilities of successs and the resultant type of an individual invitation. Therefore if the number of agents invited per invite action is foo, this method has to be called foo times.

Returns:

successful invitation: a valid computer player heuristic.
unsuccesful invitation: NONPARTICIPANT

static double ideation.Environment.successProbability_improve ( double prevIdeaValue ) [static]

This is a function of its own, so that it can be accessed by anyone who needs it outside. Thereby if we want to change this function we only have to do so here. The points in the code are neccessary because of javas handling of division for integers!

Parameters:

prevIdeaValue The quality of the idea that is to be improved.
