WebJul 7, 2024 · To handle this problem, a distributed algorithm, called distributed aggregative gradient tracking, is proposed and analyzed, where the global objective function is strongly convex, and the communication graph is balanced and strongly connected. It is shown that the algorithm can converge to the optimal variable at a linear rate.

WebMar 28, 2024 · In many cases, we use functions. Consider flipping a coin. There are two possible outcomes: heads and tails. The odds of heads and the odds of tails must add to 1, because one of them must come up. We can represent this situation with the following equation: p x ( 1 − p) 1 − x. Here x is the coin and x = 1 means heads and x = 0 if tails ... WebIn many engineering optimization problems, the number of function evaluations is severely limited by time or cost. These problems pose a special challenge to the field of global optimization, since existing methods often require more function evaluations than can be comfortably afforded.

WebNov 5, 2024 · 1 Answer. The "objective function" is the function that you want to minimise or maximise in your problem. The expression "objective function" is used in several different contexts (e.g. machine learning or linear programming ), but it always refers to the function to be maximised or minimised in the specific (optimisation) problem.

WebWhether the objective function is convex or not depends on the details of the network.
