linopy.constraints.Constraints

class linopy.constraints.Constraints(data, model, _label_position_index=None)

A constraint container used for storing multiple constraint arrays.

__init__(data, model, _label_position_index=None)

Methods

__init__(data, model[, _label_position_index])
add(constraint)	Add a constraint to the constraints constrainer.
format_labels(values[, display_max_terms])	Get a string representation of a selection of constraint labels.
get_label_position(values)	Get tuple of name and coordinate for constraint labels.
get_name_by_label(label)	Get the constraint name of the constraint containing the passed label.
items()
print_labels(values[, display_max_terms])	Print a selection of labels of the constraints.
remove(name)	Remove constraint name from the constraints.
reset_dual()	Reset the stored solution of variables.
sanitize_infinities()	Replace infinite values in the constraints with a large value.
sanitize_missings()	Set constraints labels to -1 where all variables in the lhs are missing.
sanitize_zeros()	Filter out terms with zero and close-to-zero coefficient.
set_blocks(block_map)	Get a dataset of same shape as constraints.labels with block values.
to_matrix([filter_missings])	Construct a constraint matrix in sparse format.
