(function from pyomo.contrib.mindtpy.util)

pyomo.contrib.mindtpy.util.epigraph_reformulation(exp, slack_var_list, constraint_list, use_mcpp, sense)[source]

Epigraph reformulation.

Generate the epigraph reformulation for objective expressions.

Parameters:

  • slack_var_list (VarList) – Slack vars for epigraph reformulation.

  • constraint_list (ConstraintList) – Epigraph constraint list.

  • use_mcpp (Bool) – Whether to use mcpp to tighten the bound of slack variables.

  • exp (Expression) – The expression to reformulate.

  • sense (objective sense) – The objective sense.
