We consider a geometrical approach to constructing viscosity solutions to Hamilton-Jacobi-Bellman equations. This takes the Lagrangian manifold M on which the characteristic curves for the Cauchy problem lie and forms a viscosity solution V as the minimum of the generating functions of the branches of M lying over state space. This construction is well-known in the case of finite time variation...

When solving Constraint Satisfaction Problems (CSPs), it is desirable to find multiple solutions, or to find solutions that are robust, allowing us to modify the values of variables without breaking the solution. Furthermore, we would like to be able to represent these multiple solutions in a compact manner. We present a method for improving the performance of, and solutions returned by, stocha...

We consider the structure of the number projected BCS wave function in the particle-hole basis, and use it to study several approximate treatments of pairing. The analysis is carried out for the exactly solvable Richardson model involving a pure pairing hamiltonian acting in a space of equally spaced doubly degenerate levels at half filling. 1. Inroduction Pairing correlations are ubiquitous in...
