109 * In cases of user-given expressions, higher order derivatives may not be available for the user-expression,
110 * even if the expression interpreter could handle these. This method allows to recognize that, e.g., the
111 * Hessian for an expression is not available because it contains a user expression that does not provide
141 SCIP_Bool new_varvals, /**< have variable values changed since last call to a point evaluation routine? */
148 * Since the AD code might need to do a forward sweep, variable values need to be passed in here.
166 * Returned arrays `rowidxs` and `colidxs` and number of elements `nnz` are the same as given by SCIPexprintHessianSparsity().
