Global Search Based on Efficient Diagonal Partitions and a Set of Lipschitz Constants

Abstract: Abstract. In the paper, the global optimization problem of a multidimensional "black-box" function satisfying the Lipschitz condition over a hyperinterval with an unknown Lipschitz constant is considered. A new efficient algorithm for solving this problem is presented. At each iteration of the method a number of possible Lipschitz constants is chosen from a set of values varying from zero to infinity. This idea is unified with an efficient diagonal partition strategy. A novel technique balancing usage of local… Show more

“…Moreover, if stopping tests are internalized within a method, it may not be possible to ensure all algorithms use the same stopping conditions [SS00,SK06]. However, if a fixed-cost or fixed-target approach (see Subsection 4.3) is employed, then other stopping conditions can be turned off, thereby ensuring all algorithms use the same stopping conditions.…”

“…For the S-H. Camel B. and Hartman-6 test problems PLOR performs close to the best results obtained with the DIRECT-l and only for the Shekel-5 problem PLOR took much higher amount of function evaluations comparing with the other DIRECT-type algorithms. However, it was shown in [37], that for these standard test functions DIRECT executes a very small number of trials until it generates a point in the neighborhood of the global minimizer. Moreover, the initial feasible region can also have a significant impact on this.…”
