The enumeration IloCplex::MIPEmphasisType lists the values that the MIP<br />

emphasis parameter IloCplex::MIPEmphasis can assume in an instance of<br />

IloCplex for use when it is solving MIP problems. Use these values with the method<br />

IloCplex::setParam(IloCplex::MIPEmphasis, value) when you set<br />

MIP emphasis.<br />

With the default setting of IloCplex::MIPEmphasisBalance, IloCplex tries<br />

to compute the branch & cut algorithm in such a way as to find a proven optimal<br />

solution quickly. For a discussion about various settings, refer to the <strong>ILOG</strong> <strong>CPLEX</strong><br />

User's <strong>Manual</strong>.<br />

See the reference manual <strong>ILOG</strong> <strong>CPLEX</strong> Parameters and the <strong>ILOG</strong> <strong>CPLEX</strong> User's<br />

<strong>Manual</strong> for more information about these parameters. Also see the user's manual for<br />

examples of their use.<br />
