Abstract: In this paper, the well-knwon quasi-gradient screening algorithm on optimal sequencing cascaded development of water energy resources will be introduced. Then we will given a contraexample in practice and prove the inefficiency of the algorithm in theory.

Key words: quasi-gradient, algorithm, optimal sequencing, cascaded hydroelectric station
