Changed line 12 from:
OTOL is the relative objective function tolerance for reporting a successful solution. A lower value of OTOL, such as 1e-8, will give a more precise answer but at the expense of more iterations. The default of 1e-6 is generally sufficient for most problems. However, there are times when there are multiple objectives and higher precision is required to fully resolve minor objectives. OTOL and RTOL (relative tolerance on the equations) should generally be adjusted together.

 Description: Objective function tolerance for successful solution

OTOL is the relative objective function tolerance for reporting a successful solution. A lower value of OTOL, such as 1e-8, will give a more precise answer but at the expense of more iterations. The default of 1e-6 is generally sufficient for most problems. However, there are times when there are multiple objectives and higher precision is required to fully resolve minor objectives. OTOL and RTOL (relative tolerance on the equations) should generally be adjusted together.
