OscillationDetector Class Reference

Agent for detecting non-converging oscillation in BP Objects of this class compare state vectors to previously seen state vectors If any vectors are repeating, oscillation is possible. This class uses a hashed checksum to compare state vectors (cheap) then uses explicit state comparisons (expensive) when collisions are detected in checksums. More...

Member Function Documentation

bool OscillationDetector::checkState	(	double *	a,
		double *	b
	)

Check whether state has been seen before Each state consistes of two vectors

Parameters:

[in]	a	first state vector
[in]	b	second state vector

Returns:

whether state has been seen before within epsilon tolerance

bool OscillationDetector::isOscillating

(

)

[inline]

Returns whether oscillation has been detected

Returns:

whether oscillation has been detected by a previous call to checkState()
