This is the core component that runs Flux Balance Analysis simulation for the model. There are three FBA algorithms available via COBRApy: - plain FBA, which maximize flux throug the reactions in objective; - geometric FBA, which find unique flux set that is central to the range of possible fluxes (see also (K Smallbone, E Simeonidis, 2009, DOI:10.1016/j.jtbi.2009.01.027); - parsimonious FBA, which maximize objective function but keep the total sum of fluxes at minimum (see also (Lewis et al. 2010, DOI:10.1038/msb.2010.47). By default plain FBA is selected. The output of the components are tables with objective function value, distribution of fluxes for reactions and shadow prices and the simulated model object.
