Resource augmentation in two-dimensional packing with orthogonal rotations
We consider the problem of packing two-dimensional rectangles into the minimum number of unit squares, when 90 rotations are allowed. Our main contribution is a polynomial-time al...

On complexity of multistage stochastic programs
In this paper we derive estimates of the sample sizes required to solve a multistage stochastic programming problem with a given accuracy by the (conditional sampling) sample aver...

Greedy multiprocessor server scheduling
We show that the greedy Highest Density First (HDF) algorithm is (1+ )-speed O(1)-competitive for the problem of minimizing the p norms of weighted flow time on m identical machin...

A (1-1/e)-approximation algorithm for the generalized assignment problem
We give a (1 - 1/e)-approximation algorithm for the Max-Profit Generalized Assignment Problem (Max-GAP) with fixed profits when the profit (but not necessarily the size) of every ...

A note on two-person zero-sum communicating stochastic games
For undiscounted two-person zero-sum communicating stochastic games with finite state and action spaces, a solution procedure is proposed that exploits the communication property,...
