​Optimization has lengthy been a resource of either notion and purposes for geometers, and conversely, discrete and convex geometry have supplied the principles for lots of optimization innovations, resulting in a wealthy interaction among those topics. the aim of the Workshop on Discrete Geometry, the convention on Discrete Geometry and Optimization, and the Workshop on Optimization, held in September 2011 on the Fields Institute, Toronto, was once to additional stimulate the interplay among geometers and optimizers. This quantity displays the interaction among those components.

The inspiring Fejes Tóth Lecture sequence, brought by way of Thomas Hales of the college of Pittsburgh, exemplified this method. whereas those fields have lately witnessed loads of job and successes, many questions stay open. for instance, Fields medalist Stephen Smale acknowledged that the query of the lifestyles of a strongly polynomial time set of rules for linear optimization is without doubt one of the most vital unsolved difficulties first and foremost of the twenty first century. The vast diversity of themes lined during this quantity demonstrates the numerous contemporary and fruitful connections among assorted ways, and lines novel effects and state of the art surveys in addition to open difficulties.

For m D 13, Theorem 2 implies that (5) immediately holds if xiT xj RD =2 for any i ¤ j . Assume alternatively that xiT xj Ä RD =2 for all i ¤ j .
