Value

a list of class solver with the following named ebtries:

opt,

solution,

objective,

status,

message,

solver,

version.

Arguments

objective: a numeric vector.
lower, upper: lower and upper bounds.
linCons: list of linear constraints: mat, lower, upper.
control: control list.
x_L, x_U: lower and upper box bounds.
A: linear constraints matrix.
b_L, b_U: lower and upper linear constraints bounds.
solver: a character string, the solver name.
category: a character string, the NEOS category name.
project: a character string, the AMPL project name.
inf: a numeric value, the maximum value used for bounds.
trace: a logical flag, if TRUE the optimization will be traced.
