<b>Remarks</b></p>
<P>This is a simplified way of specifying multiple eps thresholds that are "logically" consistent.<br>
It sets the following values: <A HREF="set_epsel.htm">set_epsel</A>, <A HREF="set_epsb.htm">set_epsb</A>, <A HREF="set_epsd.htm">set_epsd</A>, <A HREF="set_epspivot.htm">set_epspivot</A>, <A HREF="set_epsint.htm">set_epsint</A>, <A HREF="set_mip_gap.htm">set_mip_gap</A><br>
The default is EPS_TIGHT.</P>
<p class="label">
<b>Example</b></p>
<pre><code>#include <stdio.h>
#include <stdlib.h>
#include "lp_lib.h"
int main(void)
{

/* Create a new LP model */
