Global objective function
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. A feasible solution that minimizes (or maximizes, if that is the goal) the objective function is called an optimal solution . In mathematics, conventional optimization problems are usually stated in terms of minimization. A local minimum x* is defined as an element for which there exists some δ > 0 such that. See more Mathematical optimization (alternatively spelled optimisation) or mathematical programming is the selection of a best element, with regard to some criterion, from some set of available alternatives. It is generally divided … See more Optimization problems can be divided into two categories, depending on whether the variables are continuous or discrete: • An optimization problem with discrete variables is known … See more Fermat and Lagrange found calculus-based formulae for identifying optima, while Newton and Gauss proposed iterative methods for moving towards an optimum. The term " See more Feasibility problem The satisfiability problem, also called the feasibility problem, is just the problem of finding any See more Optimization problems are often expressed with special notation. Here are some examples: Minimum and … See more • Convex programming studies the case when the objective function is convex (minimization) or concave (maximization) and the constraint set is convex. This can be viewed as a particular case of nonlinear programming or as generalization of linear or convex quadratic … See more To solve problems, researchers may use algorithms that terminate in a finite number of steps, or iterative methods that converge to a solution (on … See more

Examples are ridge regression or SVM. You can also optimize the objective function without any loss function, e.g. simple OLS or logit. $\endgroup$

WebA global minimum is a point where the function value is smaller than or equal to the value at all other feasible points. Generally, Optimization Toolbox™ solvers find a local optimum. (This local optimum can be a global optimum.) They find the optimum in the basin of attraction of the starting point. For more information, see Basins of ...
