This is in regard to the method described here:
I was just playing with this technique a bit and found it was almost useless until "Weight" was set to 10000 for a system with ground state energy 60. I first tried out a weight of 100, but this resulted in a wavefunction overlap of about 0.0001, which was (apparently) large for purposes of computing entanglement.
With a large weight of 10,000, the overlap was below the number of significant figures of the printf statement (I think 10 digits).
Is that typical? Should I go even higher for the weight?
