[Cs5500] GBFS concern

[Ashish Joshi]

Hey guys,
I just realized that if we hand over the playground to the undergrads, it
gives them access to the
class DistanceCalc...which contains the BFS implementation for calculating
path between 2 nodes
Is that what we want?
The solve method in the teacher avatrar uses methods from the distancecalc
class
to find the layer
I'm not sure if it can be avoided...since it's part of the playground...as
in it's used in the instance and instanceset classes
So if the undergrads are to run tournaments locally then they'll need it
Let me know what you guys think?
