Operations research Symmetry in integer programming LEHIGH UNIVERSITY Jeff Linderoth OstrowskiJamesThis thesis focuses on solving integer programs whose feasible regions are highly symmetric. Symmetry has long been considered a curse in integer programming, and auxiliary (often extended) formulations are ...
Given is a set of n points with integer coordinates. Your task is to decide whether the set has a center of symmetry. A set of points S has the center of symmetry if there exists a point s (not necessarily in S) such that for every point p in S there exists a point q in S su...
order, pattern, beautiful proportion, and balance. The human body is symmetric, left and right of bilateral halves against the sagittal plane. TheVitruvian Manby Leonardo da Vinci describes the symmetry of a human body. Butterfly, fish, and birds represent the symmetry in biology. People created...

Virtually all network analyses involve structural measures between pairs of vertices, or of the vertices themselves, and the large amount of symmetry present in real-world complex networks is inherited by such measures. This has practical consequences that have not yet been explored in full generality...
