I am absolutely new to Polymer simulation. I am trying to understand the simulation by analyzing source code written by others.

Can anyone tell me what are the differences between the following three source code in terms of their objectives?

1. Monte-Carlo-simulation-of-polymers
2. PolymerPhysicsSimulation
3. Polymer-MonteCarlo

For example, I want to know:

1. if they achieve the same objectives, i.e., polymer growth.
2. if they represent bio-polymers (e.g. proteins) or synthetic polymers.
3. if they are lattice-based or off-lattice simulations.
4. if they represent hard-polymers or soft-polymers.
