ALPS evaluation in financial portfolio optimisation
No full textclaims to reduce premature convergence in Evolutionary Al-gorithms. We provide the first evaluation of ALPS on a real-world problem — the evolution of non-linear factor models for financial portfolio optimisation. We incorporate ALPS into our GP system, coupled to an investment simulator, and provide a head-to-head comparison between ALPS GP and Standard GP. By investigating the performance of ALPS both during train-ing and during out-of-sample validation, we provide empirical evidence of the benefits of ALPS; we show that it really does reduce convergence, and provides fitter individuals, in our problem domain. The ALPS GP system evolves non-linear factor models that out-perform not only the Standard GP system, but also the market index by a significant amount. I

Employment struggles and the commodification of time: Marx and the analysis of working time flexibility
No full textThis paper explores new working time arrangements around a critique of the ‘commodification of time’ to illuminate the contradictions of such new flexibilities. Two features of these new arrangements are seen as relevant for evaluating the Marx/Engels analysis. Firstly, those arguing the commodification of time represent all [can you suggest a wording that will make clear what this ‘all’ refers to?] having become a commodity outside of the processes of exchange for labour power. Significantly – and central in all working time arrangements – it is labour power that is sold, be it for a particular period of time, rather than the time itself. Hence, working time arrangements set boundaries against ‘free’ time or time in which labour power is not sold as a commodity, that ‘free’ time which was recognised in the traditional arrangements – fought over in early industrialism – which set premium payments against anti-social hours within ‘overtime’. New working time arrangements tend to blur the boundaries between ‘free’ and ‘working’ time, assuming an availability of labour power to capital. While much of the promotion of flexibility stresses the possibility of making adjustment to suit social and domestic requirements it is more usually the means for altering working time to meet the demands of capital
