title: Quick Question: Use the default value of the scipy.optimize.minimize tol parameter
body: <p>I was looking through the documentation of <code>scipy.optimize.minimize</code> for the <strong>default value of the parameter <code>tol</code></strong>, but <a href="https://docs.scipy.org/doc/scipy/reference/generated/scipy.optimize.minimize.html#scipy.optimize.minimize" rel="nofollow noreferrer">here</a> the only description of the parameter is</p>
  <blockquote>
  <p>Tolerance for termination. For detailed control, use solver-specific options.</p>
  </blockquote>
  <p>I need a way to assign a default value to the parameter, since I want the user to chose whether or not he would like to set a custom tolerance. If there should not be a tolerance set, I don't know what to put into the variable. Also, it cannot be method-specific, since the method can also be chosen by the user.
  I would save a lot of time if I knew the default value, since there are a lot of different minimize calls -&gt; if statements would make the code very ugly and quite a bit longer. Thanks!</p>
