Significance of output:

This paper proposes the first genetic algorithm for the design of Variable Length Error Correction (VLEC) codes, which are widely applicable in standardised speech, audio, image and video codecs. For the first time, this allows VLEC codes to be designed holistically, considering both their performance and their complexity. This facilitates a 50% reduction in complexity at the individual mathematical operations level, without imposing any performance degradation. The concepts described in this paper featured in a Wiley-IEEE-Press book (Near Capacity Variable Length Coding) and have subsequently inspired leading researchers in the telecommunications area at Universita di Trieste, Italy.
