title: How to change CPLEX parameters in oplrun?
body: <p>Is there a way to let <code>oplrun</code> take a specific CPLEX parameter, such as  CPX_PARAM_LPMETHOD (Linear Programming method). In <a href="http://www-eio.upc.edu/lceio/manuals/cplex-11/html/refparameterscplex/refparameterscplex110.html#277669" rel="nofollow noreferrer">the reference here</a>, it is called by various names for different languages:</p>
  
  <pre><code>C Name: CPX_PARAM_LPMETHOD
  
  C++ Name: RootAlg
  
  Java Name: RootAlg
  
  .NET Name: RootAlg
  
  InteractiveOptimizer: lpmethod 
  </code></pre>
  
  <p>But there is no reference about the OPL or oplrun.</p>
  
  <p>Is it possible to change this parameter in an <code>oplrun</code> session? Or do I have to use these other languages/interfaces?</p>
