I am not that familiar with the specific algorithms in computational quantum state optimization, but I would imagine that the most efficient distributed method would depend on the symmetry of the Hamiltonian in which you are optimizing.

Is this for a college class? I want to take that class!

Quantum mechanics, from the back of the book that nobody gets to.

I did some reading and it looks like the multi-configurational self-consistent field method suffers from poor convergence, which could be mitigated in a distributed network by each node crunching through the CSF space in parallel, with each node starting from equally spaced (in k-space) reference configuration state functions. The node that reaches the lowest non-pathological energy state wins. No block reward though Cry

Also, explain gravity. Elaborate on your answer.

This.  I asked a physicist on these forums this before and all I got was a bunch of trolling about how I was an idiot.

I'm not sure what you mean by "explaining gravity", since we still do not really know how it arises. We have excellent models for it (read: general relativity), but it's origin is still one of the big unknowns out there.

I'll have a go, given our joy at distributed GPU number squashing here.

Subject: Multi-CSF spin and space symmetry-adapted trial waveforms using combinations of determinants.

Of the different methods that are currently in use in trialing the best wavefunction of the form:

ψ = ΣICIΦI

where ΦI is a spin and space adapted configuration state function made of determinants of the form | ΦI1 ΦI2.. ΦIN |

which method (such as MCSCF, CI, MPPT, couple cluster..) is most adaptable and will realize the most gains using distributed computing to determining the CI coefficients and the LCAO-MO coefficients (describing the ΦIk. Since all these methods require transforming AO-based electron integrals to mo-based integrals, are there any optimizations that can be done in a distributed method on par and beyond the array transformations that simplify the two-electron integral list transformations with computer time proportional to N8 down to an N5 time scale?

Also, explain gravity. Elaborate on your answer.

Physics grad from top 5 US university, will answer any college level physics/engineering/math/chemistry question that I can.

There's gotta be a few of you who are not done with exams yet!
