QUARTR: A FORTRAN IV subroutine to calculate quarter life

MISQP: A Fortran Subroutine of a Trust Region SQP Algorithm for Mixed-Integer Nonlinear Programming

The Fortran subroutine MISQP solves mixed-integer nonlinear programming problems by a modified sequential quadratic programming (SQP) method. Under the assumption that integer variables have a smooth influence on the model functions, i.e., that function values do not change drastically when inor decrementing an integer value, successive quadratic approximations are applied. The algorithm is sta...

CAVAP, A FORTRAN SUBROUTINE FOR SOLVING AN ASSIGNMENT PROBLEM WITH CONCAVE OBJECTIVE by

This document describes a FORTRAN IV subroutine named CAVAP (an acronym for conCAVe Assignment Problem) which uses a branch and bound method to solve a variant of the assignment problem in which the objective to be minimized is concave. It is assumed that m tasks are to be performed and n different kinds of machines have been defined for possible use in performing them. In general a task may be...

ORTNRM - A Fortran Subroutine Package for the Solution of Linear Two-Point Boundary Value Problems

A high-performance Fortran code to calculate spin- and parity-dependent nuclear level densities

A high-performance Fortran code is developed to calculate the spinand parity-dependent shell model nuclear level densities. The algorithm is based on the extension ofmethods of statistical spectroscopy and implies exact calculation of the first and secondHamiltonianmoments for different configurations at fixed spin and parity. The proton–neutron formalism is used. We have applied the method for...
