Literary linguistics: Open Access research in English language

Strathprints makes available Open Access scholarly outputs by English Studies at Strathclyde. Particular research specialisms include literary linguistics, the study of literary texts using techniques drawn from linguistics and cognitive science.

The team also demonstrates research expertise in Renaissance studies, researching Renaissance literature, the history of ideas and language and cultural history. English hosts the Centre for Literature, Culture & Place which explores literature and its relationships with geography, space, landscape, travel, architecture, and the environment.

Abstract

In the context of water distribution system (WDS) design optimization, majority of the evolutionary algorithm models in the literature simulate solutions using demand driven analysis (DDA) based hydraulic solver and solutions that violate the nodal pressure constraints are penalized using penalty functions. The disadvantages of penalty functions are that they are case sensitive and require expertise in calibration with numerous time consuming trial runs. This paper investigates the application of a new penalty‐free multi‐objective evolutionary algorithm (PFMOEA) in the design optimization of WDS. Herein, the PFMOEA is extended to optimize problems involving pump operations, tank sizing and locations. The model succeeded in locating cheaper solutions than those previously reported in the literature that satisfy all the required constraints. Results are presented and compared to the best solution reported in the literature.
