Linearly constrained

NettetWe describe an asynchronous parallel derivative-free algorithm for linearly constrained optimization. Generating set search (GSS) is the basis of our method. At each iteration, a GSS algorithm computes a set of search directions and corresponding trial points and then evaluates the objective function value at each trial point. Asynchronous versions of the … Nettet5. feb. 2024 · Linearly Constrained Neural Networks. Johannes Hendriks, Carl Jidling, Adrian Wills, Thomas Schön.
