FVA results for the E. coli Metabolic-Expression model ME76664 using the CPLEX simplex solvers. Iterations and sum of infeasibilities for dual simplex (default) before lifting and for primal simplex after lifting. The first column lists which variable is being maximized. Lifting helps the CPLEX simplex solvers.
