Course Syllabus

Abstract

The course is devoted to heuristic and exact algorithms for combinatorial optimization problems. The prerequisites for this course are graph theory; basic data structures (vector, list, tree, heap, stack, queue etc), algorithms (DFS, BFS, binary search, sort etc) and their complexity; experience in C++ programming.
