help for path optimization

[nik_indiatimes]

hi !


my name is nikhil and i am engg student from Nagpur,India .


I am using ga for path optimisation in my final year project .


I have seen the tsp demo problem in galib


But ,in my case the requirement is different


Here , a road map consisting of nodes or intersestions connected by linls is present. The problem is to find optimum path between any requested source and destination  .I am not able to design the strategy to search for any requested path . As there can be variable number of nodes encountered in each solution of path i am not able to code the cromosomes  . 


So it will be of great help if anybody could guide me for the same .
