I have a paper on online portfolio optimization which uses sequential optimization update rule to arrive at different weights for portfolio members depending on how the timeseries unfolds. paper is available at [url removed, login to view]
a selection of algorithms are given. i need four of them (will describe in detail later) to be implemented in mathematica and one new version based on some modifications of one of the ideas. Fixed cost quotes preferred. have room for modification of quote if final details change much. have scope for further projects based on newer extensions and algo variations.
