run(self, target=None, biomass=None, substrate=None, max_knockouts=5, variable_size=True, simulation_method=<function fba at 0x2b3173134a60>, growth_coupled=False, max_evaluations=20000, population_size=200, max_results=50, use_nullspace_simplification=True, seed=None, **kwargs)[source]
Parameters

  • target (str, Metabolite or Reaction) – The design target

  • biomass (str, Metabolite or Reaction) – The biomass definition in the model

  • substrate (str, Metabolite or Reaction) – The main carbon source

  • max_knockouts (int) – Max number of knockouts allowed

  • variable_size (bool) – If true, all candidates have the same size. Otherwise the candidate size can be from 1 to max_knockouts.

  • simulation_method (function) – Any method from cameo.flux_analysis.simulation or equivalent

  • growth_coupled (bool) – If true will use the minimum flux rate to compute the fitness

  • max_evaluations (int) – Number of evaluations before stop

  • population_size (int) – Number of individuals in each generation

  • max_results (int) – Max number of different designs to return if found.

  • kwargs (dict) – Arguments for the simulation method.

  • seed (int) – A seed for random.

  • use_nullspace_simplification (Boolean (default True)) – Use a basis for the nullspace to find groups of reactions whose fluxes are multiples of each other and dead end reactions. From each of these groups only 1 reaction will be included as a possible knockout.
