+.B NLOPT_LN_COBYLA
+Local (L) derivative-free (N) optimization using the COBYLA algorithm
+of Powell (Constrained Optimization BY Linear Approximations).
+The
+.B NLOPT_LD_COBYLA
+algorithm supports both bound-constrained and unconstrained optimization,
+and also supports an arbitrary number (\fIm\fR) of nonlinear constraints
+via the
+.BR nlopt_minimize_constrained ()
+function.
.SH STOPPING CRITERIA
Multiple stopping criteria for the optimization are supported, as
specified by the following arguments to
