trcontrol: Set the Control Parameters Used by `transport`.

Description

Set the control parameters for the algorithm used by the function transport.

Usage

trcontrol(method = c("networkflow", "revsimplex", "shortsimplex", "primaldual", "aha",
          "shielding", "auction", "auctionbf"), para = list(),
          start = c("auto",          "modrowmin", "nwcorner", "russell"), 
          nscales = 1, scmult = 2,returncoarse = FALSE, a = NULL,
          b = NULL, M = NULL, N = NULL)

Value

A list with components method, para, start, nscales, scmult, returncoarse as entered or adapted/computed based on the arguments method, a, b, M, N.

Arguments

method: The algorithm to be used to compute the optimal transference plan. See details for the function transport.pgrid.
para: A list of parameters that are specific to the chosen method. See the table on the help page of the function transport.
start: If method == "revsimplex", the method for computing a starting solution.
nscales, scmult, returncoarse: The parameters for the multiscale versions of certain algorithms. See the help on transport.
a,b,M,N: The two objects a and b for which the transportation problem is to be solved or the sizes M and N of these objects. Based on the information available here, trcontrol tries hard to find reasonable values for the control parameters of the algorithm not specified directly.
