Arguments

this

the graph object

fromNodes

the start nodes

toNodes

the end nodes

avoidLeftNodes

a collection of nodes to avoid on the left

avoidRightNodes

a collection of nodes to avoid on the right

avoidLeftEdges

a collection of edges between observed nodes in the graph that should not be used on any right hand side of any trek in the trek system.

avoidRightEdges

a collection of edges between observed noes in the graph that should not be used on any right hand side of any trek in the trek system.
