In this paper, the authors consider the planning problem for a system represented as a set of interacting agents evolving along time according to explicit timing constraints. Given a goal, the planning problem is to find the sequence of actions such that the system reaches the goal state in a...

We study the gas-water transient imbibition and drainage processes in two-dimensional nanoporous media using our recently developed Lattice Boltzmann model (LBM). To describe the microscopic molecular interactions, the model employs a pseudopotential that correlates the local density and...

This paper demonstrates the existence of adverse selection in the group insurance market with no individual choice. We provide evidence against the “conventional wisdom” that group insurance mitigates adverse selection because of the mixture of high risks and low risks. We show, however,...
