Usage

1
  solnInfoCPLEX(env, lp)

Arguments

env

An object of class "cplexPtr" as returned by openEnvCPLEX. This is basically a pointer to an IBM ILOG CPLEX environment.

Value

If successful a list is returned:

method

Integer value specifying the method to produce the current solution.

type

Integer value specifying the type of current solution.

primal_feasible

Integer value specifying if the current solution is known to be primal feasible.

dual_feasible

Integer value specifying if the current solution is known to be dual feasible.

otherwise an instance of class "cplexError".
