Abstract

Students who attend the national Olympiad process join the activity with diverse programming backgrounds and experience. Thus, in the process of selecting the better students, we examine their competence, given their heterogeneous backgrounds. In various parts of this process, we may want to ``mask'' programming advantage. This may be done by posing insight tasks that require limited programming knowledge. In this paper, we display such tasks, of various levels of difficulty, and elaborate on their relevance. Particular emphasis is put on the importance of assertional observations, creative operational ideas, and suitable problem representations.

Keywords:

insight tasks, problem solving, problem representation
