Water network rehabilitation with structured messy genetic algorithm
TL;DR: A structured messy Genetic algorithm is developed, incorporating some of the principles of the messy genetic algorithm, such as strings that increase in length during the evolution of designs, to be an effective tool for the current optimization problem.

Operational Optimization of Water Distribution Systems using a Hybrid Genetic Algorithm
TL;DR: In this article, the efficiency of GA operational optimization was improved through a hybrid method which combines the GA method with a hillclimber search strategy, which proved to be superior to the pure GA in finding a good solution quickly, both when applied to a test problem and to a large existing water distribution system.

Trade-off between Total Cost and Reliability for Anytown Water Distribution Network
TL;DR: In this article, the authors investigated the application of multiobjective evolutionary algorithms to the identification of the payoff characteristic between total cost and reliability of a water distribution system using the well-known "AnyTown" network as an example.

A hybrid inverse transient model for leakage detection and roughness calibration in pipe networks
TL;DR: In this article, an inverse transient model based on a hybrid search technique was developed mainly for the detection of leaks in water distribution networks, which is formulated as a constrained optimisation problem of weighted least-squares type.

Evolutionary multi-objective optimization of the design and operation of water distribution network: total cost vs. reliability vs. water quality
TL;DR: In this paper, the authors investigated the application of multi-objective evolutionary algorithms in the identification of the pay-off characteristic between total cost, reliability and water quality of AnyTown9s water distribution system.
