find_infeasible_bounds

(function from pyomo.util.infeasible)

pyomo.util.infeasible.find_infeasible_bounds(m, tol=1e-06)[source]

Find variables whose values are outside their bounds

Uses the current model state. Variables with no values are returned as if they were infeasible.

Parameters:

  • m (Block) – Pyomo block or model to check

  • tol (float) – absolute feasibility tolerance

Yields:

  • var (VarData) – The variable that is outside its bounds

  • infeasible (int) – A bitmask indicating which bound was infeasible (1 for the lower bound or 2 for the upper bound; 4 indicates the variable had no value or a bound was undefined)
