starting solutions {transport} | R Documentation |
Compute a feasible transference plan between two mass vectors.
northwestcorner(a, b) russell(a, b, costm)
a,b |
Two numeric vectors (typically containing natural numbers) of length m and n, describing mass distributions. |
costm |
A m by n matrix of costs for moving one unit of mass. |
A list whose components are m by n matrices, viz.
assignment |
containing as (i,j)-th entry the mass assigned from origin i to destination j; |
basis |
containing as (i,j)-th entry a 1 if it is a basic entry and a 0 otherwise. |
The current implementations are in R. Computations may be slow for larger vectors a
and b
.
The computed starting solution may be degenerate, i.e. there may be basic entries where zero mass is assigned.
