Minimax objective function
Did you know?
WebProblem objects are very flexible in that they can have 0 or more constraints, and their objective can be to Minimize () a convex expression (as shown above) or to Maximize () a concave expression. The call to Problem () still does not actually solve our optimization problem. That only happens with the call to solve (). WebThe minimax strategy for global optimization is then to—at each iteration—choose a new evaluation point such that the maximum loss is decreased as much as possi- ble. This strategy is in contrast to the maximum gain strategy, which is utilized in several common global optimization algorithms, and the relation between these strategies is described.
WebMinimax refers to an optimization strategy in two-player turn-based games for minimizing the loss or cost for the worst case of the other player. For the GAN, the generator and discriminator are the two players and take turns involving updates to their model weights. WebNot surprisingly, in many cases the objective function F(s) will have several local minimizers (see, e.g., Cooper). 1.2. The generalized minimax problem (GMP) is defined by assumptions (i)-(iv) and by (vi) The facility must be established at a point of S that minimizes the maximal transportation cost maxi= .mCi ( sdi 11 ) I. Formally, GMP is ...
