Conference Proceeding
Castro-Gutierrez, J., Landa-Silva, D., & Moreno Perez, J. (2011). Nature of real-world multi-objective vehicle routing with evolutionary algorithms

The Vehicle Routing Problem with Time Windows VRPTW) is an important logistics problem which in the realworld appears to be multi-objective. Most research in this area has been carried out using classic datasets designed for the single-objective case...

Automated conversion of Web-based marriage register data into a printed format with predefined layout (2011)
Conference Proceeding
Brailsford, D. F. (2011). Automated conversion of Web-based marriage register data into a printed format with predefined layout

The Phillimore Marriage Registers for England were published in the period 1896 to 1922 and have defined a standard layout format for the typesetting of marriage data. However, not all English parish churches had their marriage registers analysed and...

Reflowable documents composed from pre-rendered atomic components (2011)
Conference Proceeding
Pinkney, A. J., Bagley, S. R., & Brailsford, D. F. (2011). Reflowable documents composed from pre-rendered atomic components

Mobile eBook readers are now commonplace in today’s society, but their document layout algorithms remain basic, largely due to constraints imposed by short battery life. At present, with any eBook file format not based on PDF, the layout of the docum... Read More about Reflowable documents composed from pre-rendered atomic components.

Hybrid heuristic for multi-carrier transportation plans (2011)
Conference Proceeding
Landa-Silva, D., Wang, Y., Donovan, P., & Kendall, G. (2011). Hybrid heuristic for multi-carrier transportation plans

This paper describes a hybrid heuristic approach to construct transportation plans for a singlecustomer multi-carrier scenario that arises at 3T Logistics Ltd, a UK company that provides outsourced transportation planning and management services. The... Read More about Hybrid heuristic for multi-carrier transportation plans.

Comparing System Dynamics and Agent-Based Simulation for tumour growth and its interactions with effector cells (2011)
Conference Proceeding
Figueredo, G. P., & Aickelin, U. (2011). Comparing System Dynamics and Agent-Based Simulation for tumour growth and its interactions with effector cells

There is little research concerning comparisons and combination of System Dynamics Simulation (SDS) and Agent Based Simulation (ABS). ABS is a paradigm used in many levels of abstraction, including those levels covered by SDS. We believe that the est...

Into the wild: challenges and opportunities for field trial methods (2011)
Conference Proceeding
Brown, B., Reeves, S., & Sherwood, S. (2011). Into the wild: challenges and opportunities for field trial methods

Field trials of experimental systems `in the wild' have developed into a standard method within HCI - testing new systems with groups of users in relatively unconstrained settings outside of the laboratory. In this paper we discuss methodological cha... Read More about Into the wild: challenges and opportunities for field trial methods.

Comparing hybrid constructive heuristics for university course timetabling (2011)
Conference Proceeding
Landa-Silva, D., & Obit, J. H. (2011). Comparing hybrid constructive heuristics for university course timetabling

This extended abstract outlines four hybrid heuristics to generate initial solutions to the University course timetabling problem. These hybrid approaches combine graph colouring heuristics and local search in different ways. Results of experiments u...

Designing difficult office space allocation problem instances with mathematical programming (2011)
Conference Proceeding
Ulker, O., & Landa-Silva, D. (2011). Designing difficult office space allocation problem instances with mathematical programming

Office space allocation (OSA) refers to the assignment of room space to a set of entities (people, machines, roles, etc.), with the goal of optimising the space utilisation while satisfying a set of additional constraints. In this paper, a mathematic... Read More about Designing difficult office space allocation problem instances with mathematical programming.

A heuristic algorithm for nurse scheduling with balanced preference satisfaction (2011)
Conference Proceeding
Constantino, A. A., Landa-Silva, D., Luiz de Melo, E., & Romao, W. (2011). A heuristic algorithm for nurse scheduling with balanced preference satisfaction

This paper tackles the nurse scheduling problem with balanced preference satisfaction which consists of generating an assignment of shifts to nurses over a given time horizon and ensuring that the satisfaction of nurses personal preferences for shift...

Principal component analysis of image gradient orientations for face recognition (2011)
Conference Proceeding
Tzimiropoulos, G., Zafeiriou, S., & Pantic, M. (2011). Principal component analysis of image gradient orientations for face recognition

We introduce the notion of Principal Component Analysis (PCA) of image gradient orientations. As image data is typically noisy, but noise is substantially different from Gaussian, traditional PCA of pixel intensities very often fails to estimate reli...

Congestion aware forwarding in delay tolerant and social opportunistic networks (2011)
Conference Proceeding
Radenkovic, M., & Grundy, A. (2011). Congestion aware forwarding in delay tolerant and social opportunistic networks. In 2011 Eighth International Conference on Wireless On-Demand Network Systems and Servicesdoi:10.1109/WONS.2011.5720201

We propose an approach for opportunistic forwarding that supports optimization of multipoint high volume data flow transfer while maintaining high buffer availability and low delays. This paper explores a number of social, buffer and delay heuristics... Read More about Congestion aware forwarding in delay tolerant and social opportunistic networks.

Recent results [18] have shown that sparse linear representations of a query object with respect to an overcomplete basis formed by the entire gallery of objects of interest can result in powerful image-based object recognition schemes. In this paper... Read More about Sparse representations of image gradient orientations for visual recognition and tracking.
