PS-algol is a dialect of algol for the programming of problems that would normally require a database management system. It supports a persistent heap, and an associative store; it has embedded within the language features to support tasks normally carried out by filing systems or database management systems.
10 hyper-code target configuration documentation link back to documentation links to related hyper-code links to components another version Figure 11. System documentation with links hyper-code and configuration information ensure that all are kept in lock-step and consistent with one another. This does not ensure that documentation is accurate, since that… (More)
PS-algol is the first language in a family that introduces the concept of persistence as a property of data. The persistence of data is the time extent over which the data may be used. This paper introduces the general design principles for persistent programming languages and describes our first attempt, PS-algol
Much research has been carried out into solving routing problems using both Evolutionary Techniques and other methods. In this paper the authors investigate the usage of an Evolutionary Algorithms to solve the Street-Based Routing Problem (SBRP). The SBRP is a subset of the Travelling Salesman Problem that deals specifically with a street-based environment.… (More)
Street based routing (SBR) is a real-world inspired routing problem that builds routes within an urban area for mail deliveries. The authors have previously attempted to solve this problem using an Evolutionary Algorithm (EA). In this paper the authors examine a heuristic mutation based on concept of building blocks. In this case a building block is defined… (More)
This paper investigates the solving of a real world routing problem using evolutionary algorithms embedded within a Multi-agent system (MAS). An architecture for the MAS is proposed and mechanisms for controlling the interactions of agents are investigated. The control mechanism used in the final solution is based on the concept of agents submitting bids to… (More)
