GDLS

General concept

Current strain design algorithms are currently too costly to predict more than a few network modifications which would growth-couple the secretion of a product. This computation could be simplified using a local search gene deletion mutants with a desired phenotype can be iteratively improved through subsequent gene deletions, until a user defined number of alterations have been made. A heuristic approach is defined in which the user decides the k number of genetic manipulations and the number of M best solutions desired. Then MILP is use used to make at most k genetic changes and save the M best solutions. The M best solutions are used as new starting points for at most k changes. This is iterated until no more improved solutions are found. This method allows for faster computation of more complex gene modification sets, but may not find global optima.
