RandomWalkOperator with reflecting boundary can grind to a halt #405

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
A RandomWalkOperator can grind BEAST to a halt when the windowSize gets very 
large with respect to fixed bounds on the parameter. Presumably the acceptance 
rate doesn't improve but the autooptimize keeps on increasing the WindowSize 
causing the reflection to take longer and longer.

Possible solutions are 1) always default to absorbing boundary, 2) only use 
relecting boundary when there is 1 boundary. 3) Limit the windowSize to the 
parameter's range.
