.. _BayesianOptimization.parameter_distribution.constraint.name:


name (str)
""""""""""

   Default: This value has no default and must be provided

.. _BayesianOptimization.parameter_distribution.constraint.expression:


expression (str)
""""""""""""""""
   A string defining an inequality constraint in the form `a <= b` or `a >= b`. The expression can contain numbers as either integers or floating-point reals in standard or exponential notation (``0.0012`` or ``1.2E-3``) as well as the constants ``E`` (Euler constant) and ``PI`` (:math:`\pi`). Parameter names may not start with the capital letters "``E``" nor "``PI``". Supported operations are ``+``, ``-``, ``*``, ``/``, ``^``, supported single-argument functions are ``sqrt``, ``sinh``, ``sin``, ``asinh``, ``asin``, ``cosh``, ``cos``, ``acosh``, ``acos``, ``tanh``, ``tan``, ``atanh``, ``atan``, ``exp``, ``log10``, ``log``, ``erfinv``, ``erf``, ``abs``, ``trunc``, ``round``, ``sign``, and supported multi-argument functions are ``max``, ``min``.
