i've just realise that i work better with cpp because this is the only programming strategy i've known until now; ie. structural abstraction of programming/object orientation. reading http://ciips.ee.uwa.edu.au/~morris/Year2/PLDS210/strategies.html then realised that i have very little knowledge of functional programming, how to construct object and methods in programming.

thus i will bring couple of questions about agent's algo (which p has successfully run it 1,5 mth ago), questions emerge from object oriented strategy.
then soon after, i will put up p's algo complete with comments.
