Black-Box Optimization in Railway Simulations

2020
In railway timetabling one objective is that the timetable is robust against minor delays. One way to compute the robustness of a timetable is to simulate it with some predefined delays that occur and are propagated within the simulation. These simulations typically are complex and do not provide any information on the derivative of an objective ...

Toward the optimization of a class of black box optimization algorithms

Proceedings Ninth IEEE International Conference on Tools with Artificial Intelligence, 2002
Many black box optimization algorithms have sufficient flexibility to allow them to adapt to the varying circumstances they encounter. These capabilities are of two primary sorts: user-determined choices among alternative parameters, operations, and logic structures; and the algorithm-determined alternative paths chosen during the process of seeking a ...

A Model for Analyzing Black-Box Optimization

2003
The design of heuristics for NP-hard problems is perhaps the most active area of research in the theory of combinatorial algorithms. However, practitioners more often resort to local-improvement heuristics such as gradient-descent search, simulated annealing, tabu search, or genetic algorithms.

Benchmarking of Continuous Black Box Optimization Algorithms

Evolutionary Computation, 2012
Benchmarking of optimization algorithms is necessary to quantitatively assess the performance of optimizers and to understand their strengths and weaknesses. The Black Box Optimization Benchmarking (BBOB) workshops that took place in 2009, 2010, and 2012 during the Genetic and Evolutionary Computation Conference (GECCO) were set up to benchmark both ...

Round Optimal Black-Box “Commit-and-Prove”

2018
Motivated by theoretical and practical considerations, an important line of research is to design secure computation protocols that only make black-box use of cryptography. An important component in nearly all the black-box secure computation constructions is a black-box commit-and-prove protocol.

Black-box structural optimization of a mechanical component

Computers & Industrial Engineering, 2007
The aim of this paper is twofold. First, we wish to bring to the attention of the Industrial Engineering community a challenging industrial problem, black-box structural design, which cannot currently be satisfactorily addressed by professional software for topology optimization.
