Lower-level access to the RELAX-IV algorithm

.RELAX_IV provides low-level access to the FORTRAN; taking the exact input as the FORTRAN code. It does NOT do any input checking.

Usage

.RELAX_IV(n1, na1, startn1, endn1, c1, u1, b1, rc1, crash1, large1)

n1: Number of nodes
na1: Number of arcs
startn1: Starting nodes
endn1: Ending nodes
c1: Costs vector
u1: Capacities
b1: Demands
rc1: Reduced Costs
crash1: Set crash1 equal to 1 to activate an auction/shortest path subroutine for getting the initial price-flow pair. this is recommended for difficult problems where the default initialization yields long solution times. Default is 0.
large1: A very large integer to represent infinity

A list containing all parameters, as well as x1 which contains the solution, and feasible1 which contains a flag for feasibility.
