The use of a biased heuristic by a genetic algorithm applied to the design of multipoint connections in a local access network

This paper presents a genetic algorithm for finding a constrained minimum spanning tree. The problem is of relevance in the design of minimum cost communication networks, where there is a need to connect all the terminals at a user site to a terminal concentrator in a multipoint (tree) configuration, while ensuring that link capacity constraints are not violated. The approach used maintains a distinction between genotype and phenotype, which produces superior results to those found using a direct representation in a previous study.

Private purpose trusts: a reform proposal

Argues for the introduction of statutory reform to enable valid private purpose trusts to be created by those wishing to make testamentary gifts for non-charitable purposes, with no human beneficiary. Examines the rationale employed in cases where the validity of a private purpose trust has been upheld despite the absence of a human beneficiary. Considers the approaches adopted by five offshore jurisdictions when introducing purpose trust legislation. Identifies key features to be included in any new purpose trust legislation introduced in the UK.

Pre-nups: precedents in need of reform?

Traces the development of the law relating to the enforceability of pre-nuptial agreements, given the potential conflict between such an agreement and the jurisdiction of the court to determine financial provision on divorce. Sets out the 16 point checklist laid down by K v K (Ancillary Relief: Prenuptial Agreement) against which the enforceability of an agreement should be judged. Comments on the significance given to the pre-nuptial agreement in ancillary relief proceedings in Crossley (Susan) v Crossley (Stuart), where the parties were required to show why the agreement should, or should not, determine the outcome of the proceedings.

Financing the development of poor communities in the Northern Cape of South Africa - an analytical framework for the study of livestock banks

This paper is part of a major project about the Northern Cape Land Reform and Advocacy (NCLRA) programme being implemented by FARM-Africa* in South Africa. The NCLRA programme had initiated a financial mechanism to help poor communities to get access to finance and training in order to enable them to make better use of their newly-acquired land. One prominent aspect of the programme is the implementation of Livestock Banks, or the use of animals as financial products. The paper provides an analytical framework with which to evaluate the effectiveness of Livestock Banks in the poor communities of the Northern Cape in South Africa. It focuses on the design, implementation and future of Livestock Banks. The paper argues that Livestock Banks need to be reformed and enhanced if they are to continue to play a key role in the goal of creating financial and economic value in Africa, particularly when the primary objective is simultaneously to help reduce poverty.

FARM-Africa South Africa Northern Cape land reform and advocacy programme 2004-2008: final evaluation

FARM-Africa South Africa has played a crucial and important role in filling the gap that existed after the return of land to communities by government in the Northern Cape. Their support to farmer communities during the post-settlement phase has been critical for making productive use of land. During 2004-2008, FARM-SA has worked in 20 community projects in the Northern Cape, benefiting 745 poor households.
