GurobiPersistent

Interface

GurobiPersistent(**kwds)

A class that provides a persistent interface to Gurobi.

Methods

GurobiPersistent.add_block(block)	Add a single Pyomo Block to the solver's model.
GurobiPersistent.add_constraint(con)	Add a single constraint to the solver's model.
GurobiPersistent.set_objective(obj)	Set the solver's objective.
GurobiPersistent.add_sos_constraint(con)	Add a single SOS constraint to the solver's model (if supported).
GurobiPersistent.add_var(var)	Add a single variable to the solver's model.
GurobiPersistent.available([exception_flag])	Returns True if the solver is available.
GurobiPersistent.has_capability(cap)	Returns a boolean value representing whether a solver supports a specific feature.
GurobiPersistent.has_instance()	True if set_instance has been called and this solver interface has a pyomo model and a solver model.
GurobiPersistent.load_vars([vars_to_load])	Load the values from the solver's variables into the corresponding pyomo variables.
GurobiPersistent.problem_format()	Returns the current problem format.
GurobiPersistent.remove_block(block)	Remove a single block from the solver's model.
GurobiPersistent.remove_constraint(con)	Remove a single constraint from the solver's model.
GurobiPersistent.remove_sos_constraint(con)	Remove a single SOS constraint from the solver's model.
GurobiPersistent.remove_var(var)	Remove a single variable from the solver's model.
GurobiPersistent.reset()	Reset the state of the solver
GurobiPersistent.results_format()	Returns the current results format.
GurobiPersistent.set_callback([func])	Specify a callback for gurobi to use.
GurobiPersistent.set_instance(model, **kwds)	This method is used to translate the Pyomo model provided to an instance of the solver's Python model.
GurobiPersistent.set_problem_format(format)	Set the current problem format (if it's valid) and update the results format to something valid for this problem format.
GurobiPersistent.set_results_format(format)	Set the current results format (if it's valid for the current problem format).
GurobiPersistent.solve(*args, **kwds)	Solve the model.
GurobiPersistent.update_var(var)	Update a single variable in the solver's model.
GurobiPersistent.version()	Returns a 4-tuple describing the solver executable version.
GurobiPersistent.write(filename)	Write the model to a file (e.g., and lp file).
