The parameter can be read at any time if you have access to the  
EvolutionState.  You can say:

int val = state.parameters.getInt(new Parameter("custom.BinInt- 
size"), null);

But you shouldn't do this over and over again, it's expensive.   
Instead, you should do it during your Problem's setup(...) method:

int val;
public void setup(EvolutionState state, Parameter base)
	super.setup(state, base);
	val = state.parameters.getInt(new Parameter("custom.BinInt-size"),  
	... other parameter setup goes here ...
