Summary: The global optimization problem with simple bounds which is the scope of this work can be defined in general as \(\min_{x\in X}f(x)\) where \(X\) is a – possibly multidimensional – interval. The original problem can be solved with verified accuracy with the aid of interval subdivision methods. These algorithms are based on the well-known branch-and-bound principle. The methods pruning the search tree of these algorithms are the so-called accelerating devices. One of the most effective of these is the interval Newton step, however, its time complexity is relatively high as compared with other accelerating devices. Therefor it should only be deployed if there are no other possibilities to effectively bound the search tree. Methods like the boxing method can decrease the number of the applied Newton steps. The present paper discusses some of these methods and shows the numerical effects of their implementation.
