Usually lifeline systems, such as water distribution network and gas supply network, cover large areas. For these systems, network topology design based on seismic reliability provides a good way to design new systems and update old ones. In this paper, a topology optimization model for lifeline networks is established. The aim of the model is to find the least-cost network topology while its s...

This paper presents a new simulated annealing algorithm to solve constrained multi-global optimization problems. To compute all global solutions in a sequential manner, we combine the function stretching technique with the adaptive simulated annealing variant. Constraint-handling is carried out through a nondifferentiable penalty function. To benchmark our penalty stretched simulated annealing ...

In this paper, the author proposes the application of a genetic algorithm and simulated annealing to solve the network planning problem. Compared with other optimisation methods, genetic algorithm and simulated annealing are suitable for traversing large search spaces since they can do this relatively rapidly and because the use of mutation diverts the method away from local minima, which will ...

The evolution of the crystallographic texture in lowcarbon steels from a deformed state to a full recrystallization (RX) state upon annealing is an issue with both academic and practical importance.1–4) Normally, the dominant components in the cold-rolled (CR) texture, {hkl}<110> , vanish after RX. Conversely, the RX texture, consisting of varying intensities of {001}, {111} and {011}...
