Set overlapping size: 10, 20, and 40, in all instances.
Adding noise to second half: {0(i.e. no noise), 0.01, 0.1, 1} *
randn(half,3) in all instances
Display and compare two methods:
a)      shortest path-based
b)      superimposing overlapping region
Then, generate a summary graph comparing the errors of the two methods
on the different problems.
