Using real-world geospatial data with evolutionary algorithms. (2010)
Presentation / Conference Contribution
Urquhart, N. B. (2010, January). Using real-world geospatial data with evolutionary algorithms. Paper presented at Universities' Transport Study Group

Developments in the field of Geographical Information Systems (GIS) have increased the availability of on-line road network data and associated routing services. The ability to integrate such data and services into web sites and other business system... Read More about Using real-world geospatial data with evolutionary algorithms..

Application of CoSMoS parallel design patterns to a pedestrian simulation. (2009)
Presentation / Conference Contribution
Clayton, S., Urquhart, N. B., & Kerridge, J. (2009, September). Application of CoSMoS parallel design patterns to a pedestrian simulation. Presented at International Conference on Parallel Processing and Applied Mathematics PPAM 2009: Parallel Processing and Applied Mathematics

In this paper, we discuss the implementation of a simple pedestrian simulation that uses a multi agent based design pattern developed by the CoSMoS research group. Given the nature of Multi Agent Systems (MAS), parallel processing techniques are inev... Read More about Application of CoSMoS parallel design patterns to a pedestrian simulation..

Minimization of incompletely specified mixed polarity Reed Muller functions using genetic algorithm. (2009)
Presentation / Conference Contribution
Al-Jassani, B. A., Urquhart, N. B., & Almaini, A. E. A. (2009). Minimization of incompletely specified mixed polarity Reed Muller functions using genetic algorithm. . https://doi.org/10.1109/12.67320

A New and efficient Genetic Algorithm (GA) based approach is presented to minimise the number of terms of Mixed Polarity Reed Muller (MPRM) single and multi output incompletely specified Boolean functions. The algorithm determines the allocation of d... Read More about Minimization of incompletely specified mixed polarity Reed Muller functions using genetic algorithm..

CO2Y the intelligent green solution: minimising carbon emissions by maximising shared travel opportunity. (2009)
Presentation / Conference Contribution
Urquhart, N. B., McEwan, T., Holden, R., & Vogogias, T. (2009, May). CO2Y the intelligent green solution: minimising carbon emissions by maximising shared travel opportunity. Paper presented at Scottish Transport Applications Research Conference

It is in the interests of everybody that the environment is protected. In view of the recent leaps in environmental awareness it would seem timely and sensible, therefore, for people to pool vehicle resources to minimise the damaging impact of emissi...

This paper presents new techniques and algorithms to compute and optimize Mixed Polarity Reed Muller logic functions (MPRM) using Tabular techniques and Genetic Algorithms (GA). The first algorithm is used for bidirectional conversion between Fixed P... Read More about Optimization of MPRM functions using tabular techniques and genetic algorithms..

Carbon-friendly travel plan construction using an evolutionary algorithm (2007)
Presentation / Conference Contribution
Urquhart, N. B., & Urquhart, N. B. (2007, July). Carbon-friendly travel plan construction using an evolutionary algorithm. Presented at Proceedings of the 9th annual conference on Genetic and evolutionary computation - GECCO '07

This paper discusses the use of an evolutionary algorithm to design workplace travel plans, to promote car sharing and reduce carbon emissions from single-occupancy motor vehicles.

Building distribution networks using cooperative agents. (2006)
Book Chapter
Urquhart, N. B. (2006). Building distribution networks using cooperative agents. In J. Rennard (Ed.), Handbook of Research on Nature Inspired Computing for Economics and Management (465-482). Idea Group Reference. https://doi.org/10.4018/978-1-59140-984-7.ch037

This chapter examines the use of emergent computing to optimize solutions to logistics problems. The chapter initially explores the use of agents and evolutionary algorithms to optimize postal distribution networks. The structure of the agent communi...

Real-time construction of aircraft landing schedules using an evolutionary algorithm (2006)
Presentation / Conference Contribution
Urquhart, N. (2006, July). Real-time construction of aircraft landing schedules using an evolutionary algorithm. Presented at Proceedings of the 8th annual conference on Genetic and evolutionary computation - GECCO '06, Seattle, Washington, USA

This poster investigates the use of Evolutionary Algorithms (EAs) to optimise solutions to the Dynamic Aircraft Landing Problem (DALP). The approach adopted here uses an EA to evolve improvements to the solution so as to move towards an optimum solut...
