Returns
find_active_constraints(x, lb, ub, rtol=1e-10)

The threshold is computed using :None:None:`rtol` and the absolute value of the closest bound.

Returns

active : ndarray of int with shape of x

Each component shows whether the corresponding constraint is active:

  • 0 - a constraint is not active.

  • -1 - a lower bound is active.

  • 1 - a upper bound is active.

Determine which constraints are active in a given point.

Examples

See :

Local connectivity graph

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.

Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)

SVG is more flexible but power hungry; and does not scale well to 50 + nodes.

All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
