linopy.constraints.Constraints

class linopy.constraints.Constraints(data=<factory>, model=None)

A constraint container used for storing multiple constraint arrays.

__init__(data=<factory>, model=None)

Methods

__init__([data, model])
add(constraint)	Add a constraint to the constraints constrainer.
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()
iter_ravel(key[, broadcast_like, ...])	Create an generator which iterates over all arrays in key and flattens them.
print_labels(values[, display_max_terms])	Print a selection of labels of the constraints.
ravel(key[, broadcast_like, ...])	Ravel and concate all arrays in key while aligning to broadcast_like.
remove(name)	Remove constraint name from the constraints.
reset_dual()	Reset the stored solution of variables.
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.
