Gridlink Description

Gridlink is a tool for manipulating the rectangular link diagrams which were introduced as variant forms of arc presentations. You can use it by generating a knot model and making the required changes. Any rectangular diagram of an unknot or split link can be monotonically reduced to a trivial diagram by a sequence of elementary moves. You can display the number of windings and their coordinates in order to capture a snapshot of the model.
