Optimal risk-sharing in private and collective pension contracts
Pension solidarity can no longer be taken for granted. Due to demographic changes - and hence a growing retiree/employee ratio - additional contributions offer steadily fewer opportunities for clearing pension...

On when to stop sampling for the maximum
Suppose a sequential sample is taken from an unknown discrete probability distribution on an unknown range of integers, in an effort to sample its maximum. A crucial issue is an appropriate stop** rude deter...

The Design of Interactive Decision Support Systems
In the Netherlands there is a national research project to design “Decision Support Systems” (DSS). This research project is subsidized by the National Facility of Informatics (NFI). Several universities and c...

Hit-and-run algorithms for the identification of nonredundant linear inequalities
Two probabilistic hit-and-run algorithms are presented to detect nonredundant constraints in a full dimensional system of linear inequalities. The algorithms proceed by generating a random sequence of interior...

Bayesian stop** rules for multistart global optimization methods
By far the most efficient methods for global optimization are based on starting a local optimization routine from an appropriate subset of uniformly distributed starting points. As the number of local optima i...

A Stochastic Approach to Global Optimization
Letf : Rn → R be a real valued smooth objective function. The area of nonlinear programming is traditionally concerned with methods that find a local optimum (say local minimum) of f, i.e. a point x* e Rn such th...

A stochastic method for global optimization
A stochastic method for global optimization is described and evaluated. The method involves a combination of sampling, clustering and local search, and terminates with a range of confidence intervals on the va...
