Returns a modified version of paths
, where
component paths/cycles are reoriented so low weight edges occur first, and the component paths/cycles are then permuted so lowweight paths are first.

A 
path1 
A vector giving a hamiltonian.
This will be the first path of the returned hamiltonian. The default is obtained from 
paths 
A matrix where each row is a hamiltonian. Default comes from 
matrix

If 
path_weight 
A function used combine path weights into a single value. Default function is 
path_dir 
A function used to evaluate a path start and orientation. 
... 
passed to 
If path
is not provided, find the hamiltonian (path for even n, cycle for odd n) with the smallest total
weight. Applying path_dir
to edge weights, pick the starting and point orientation for path1 giving the largest path_dir
value. (For open paths, there are only two possible starts, for cycles there are n).
Apply this node labelling to the hamiltonians in the rows of paths.
Use criterion path_dir
again to find the best orientation for each of rows 2... of paths and
permute these rows in order of increasing path_weight
