title: Is there an easy-to-use 0-1 IP solver for java?
body: <p>I would like to use a 0-1 integer programming solver as a tool in a java program. I cannot find anything easy to use on the web. I tried the pseudo-boolean library from sat4j but this is not well documented, some classes are not consistent with their description in the API (some methods signature are different).</p>
  
  <p>Would you have any suggestion?</p>
