Box-Splitting strategies for the interval Gauss-Seidel step in a global optimization method

  title={Box-Splitting strategies for the interval Gauss-Seidel step in a global optimization method},
  author={D. Ratz},
We consider an algorithm for computing verified enclosures for all global minimizersx * and for the global minimum valuef *=f(x *) of a twice continuously differentiable functionf:ℝ n →→ within a box [x]∈I→. Our algorithm incorporates the interval Gauss-Seidel step applied to the problem of finding the zeros of the gradient off. Here, we have to deal with the gaps produced by the extended interval division. It is possible to use different box-splitting strategies for handling these gaps… CONTINUE READING
