Indeed, there are striking differences between linear programming and semidefinite programming as there are between classical and quantum computation. There has been increased research activity in optimization concerning generalizing theory and algorithms for linear programming to much wider classes of optimization problems such as semidefinite programming.

Of course, “physically impossible” is dependent on the theory that is a faithful description of nature.

Habilitation a Diriger des Wikora We create a protocol filter using cheating strategies, some of which build upon known strategies and others are based on convex optimization and linear algebra.
