A discrete-time, nonlinear, deterministic model for an open-access fishery is developed and the equilibrium is characterized. The open- access exploitation of North Sea herring during the period 1963-77 is analyzed. Alternative production functions are considered and estimated for the Norwegian...

We pose three Knapsack Problems (KPs) to select the rank-maximizing subset of wines subject to budget and quantity constraints. The first problem seeks the subset of wines, from a single cultivar (zinfandel) that maximizes the sum of rank subject to a budget constraint. We modify this problem by...
