SparseLP_old(c, polyhedron, zeps, max_warm_start)

Compute the sparsest solution of a linear program (LP) min c’x s.t. Sx=b

lb <= x <= ub

findMinimalSetOfRxns(model)

This function finds the minimal set of reactions subject to a LP objective function \(min ||x||_0\) \(min c'x\) s.t. \(Sx = b\) \(lb <= x <= ub\)

USAGE

[result_tab, sol, lprxns, l1rxns, l0rxns] = findMinimalSetOfRxns (model)

INPUT

model – COBRA model structure

OUTPUTS

• resutl_tab – number of reactions obtained for each condition

• sol – x - solution vector

• lprxns – rxns indices for LP solution

• l1rxns – rxns indices for L1 solution

• l0rxns – rxns indices for L0 solution
