Abstract
The ratios of the values of objective functions for optimal solutions of linear and integer knapsack problems are considered. Estimates for these ratios are obtained. One-dimensional and multi-dimensional knapsack problems with Boolean variables are studied experimentally. For these problems, a hypothesis is formulated on the asymptotic behavior of the ratio as the number of variables grows.
