<h1>Options Menu</h1>

<p>The options menu provides a list of settings to
control the behavior of the model-checker. The options
are:
<ul>
<li><b>Search Order:</b> perform (symbolic) state-space exploration in
breadth-first or depth-first order.</li>
<li><b>State Space Reduction:</b>Determines whether control-structure
analysis to reduce the space requirements should be
performed. Possible values are <em>none</em>, <em>conservative</em>,
and <em>aggressive</em>. There is a tradeoff between space requirement
and speed.</li>
<li><b>State Space Representation:</b>Choose how the state space
should be represented in the model checker. Possible values are
<em>DBM</em> (Difference Bound Matrices), the <em>Compact Data
Structure</em>, <em>Under Approximation</em> (bit-state hashing), and
<em>Over Approximation</em> (convex-hull).</li>
<li><b>Clock Reduction:</b> use (in-)active clock reduction.</li>
<li><b>Reuse State-Space:</b> if possible, reuse the generated
  portion of the state-space when when several
  properties of the same system are checked.</li>
<li><b>Diagnostic Trace:</b> generate a trace (if there is one)
  that shows how the checked property is (or is not)
  satisfied. The trace is automatically loaded into the
  simulator.</li>
</ul>
</p>

<p><b>Note:</b> there are certain dependencies restricting how the
various options can be combined. Activating one option may therefore
deactivate other options. The Options menu is always updated to show
the currently activated options.</p>
