Abstract

After publication of our paper Etude on theme of Dijkstra in September issue of v.35 of SIGACT News [1], we had a very interesting communication with Dr. John Hershberger related to the topic of the paper. Etude was not a research paper, but presented a tutorial for undergraduate students who are engaged with programming contests (like ACM ICPC). The tutorial was a part of a special undergraduate course at Novosibirsk State University (Russia) and was based on E. Dijkstra's heuristic search solution of non-crossing matching problem on the plane.
