Unconstrained Optimization Packages

MINPACK	Authors	Jorge Moré, Argonne National Laboratory Burt Garbow, Argonne National Laboratory Ken Hillstrom, Argonne National Laboratory

	Platform	Any machine with a reasonable amount of memory and a Fortran compiler.
	Remarks	Minpack includes software for solving nonlinear equations and nonlinear least squares problems. Five algorithmic paths each include a core subroutine and an easy-to-use driver. The algorithms proceed either from an analytic specification of the Jacobian matrix or directly from the problem functions. The paths include facilities for systems of equations with a banded Jacobian matrix, for least squares problems with a large amount of data, and for checking the consistency of the Jacobian matrix with the functions. The directory of MINPACK contains the double-precision versions.
