1. A method for determining candidates for gene deletions and additions using a model of a metabolic network associated with an organism, the method comprising:
- providing a model in a computer comprising an electronic representation of a plurality of metabolic reactions defining metabolite relationships;
selecting at least one bioengineering objective function for the organism;
selecting at least one cellular objective function for the organism;
forming a linear optimization problem that couples the at least one cellular objective function with the at least one bioengineering objective function;
executing commands in a suitably programmed computer for solving the linear optimization problem to provide an optimal solution for the bioengineering objective function that simultaneously requires optimality of the cellular objective function and yields at least one candidate gene deletion; and
providing a visual output of the at least one candidate gene deletion to a user.
