Purpose

nag_glopt_bnd_mcs_optget_int (e05jkc) is used to get the value of an integer nag_glopt_bnd_mcs_solve (e05jbc) optional parameter. nag_glopt_bnd_mcs_optget_int (e05jkc) can be used before or after calling nag_glopt_bnd_mcs_solve (e05jbc), but the initialization function nag_glopt_bnd_mcs_init (e05jac) must have been called before calling nag_glopt_bnd_mcs_optget_int (e05jkc).

Specification

#include <nag.h>
#include <nage05.h>
void  nag_glopt_bnd_mcs_optget_int (const char *optstr, Integer *ivalue, Nag_E05State *state, NagError *fail)

Description

nag_glopt_bnd_mcs_optget_int (e05jkc) obtains the current value of an integer-valued optional parameter. For example 
e05jkc ('Local Searches Limit', &loclim, &state, &fail);
will result in the value of the optional parameter Local Searches Limit being output in loclim.
The default values of the optional parameters Function Evaluations Limit, Splits Limit and Static Limit depend on the problem parameter nr (the number of non-fixed variables). A default value for each of these optional parameters will be set in the first call to the solver nag_glopt_bnd_mcs_solve (e05jbc): before that time, getting the value of any of these optional parameters using nag_glopt_bnd_mcs_optget_int (e05jkc) will not return a meaningful result.
A complete list of optional parameters, their symbolic names and default values is given in Section 12 in nag_glopt_bnd_mcs_solve (e05jbc).

Arguments

1:     optstr – const char *Input
On entry: a string identifying an integer-valued optional parameter (as described in Section 12 in nag_glopt_bnd_mcs_solve (e05jbc)).
2:     ivalue – Integer *Output
On exit: if fail.code= NE_NOERROR on exit, ivalue contains the integer value associated with the optional parameter in optstr.
3:     state – Nag_E05State *Communication Structure
state contains information required by other functions in this suite. You must not modify it directly in any way.
4:     fail – NagError *Input/Output
The NAG error argument (see Section 3.7 in How to Use the NAG Library and its Documentation).

Error Indicators and Warnings

NE_ALLOC_FAIL
Dynamic memory allocation failed.
See Section 2.3.1.2 in How to Use the NAG Library and its Documentation for further information.
NE_BAD_PARAM
On entry, argument value had an illegal value.
NE_INTERNAL_ERROR
An internal error has occurred in this function. Check the function call and any array sizes. If the call is correct then please contact NAG for assistance.
See Section 2.7.6 in How to Use the NAG Library and its Documentation for further information.
NE_NO_LICENCE
Your licence key may have expired or may not have been installed correctly.
See Section 2.7.5 in How to Use the NAG Library and its Documentation for further information.
NE_NOT_INIT
Initialization function nag_glopt_bnd_mcs_init (e05jac) has not been called.
NE_OPT_NOT_READ
The supplied optional parameter is invalid. A keyword or keyword combination was not recognized.

7
Accuracy

Not applicable.

8
Parallelism and Performance

nag_glopt_bnd_mcs_optget_int (e05jkc) is not threaded in any implementation.
