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...

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...

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

An initialization subroutine for DAEs solvers: DAEIS

Numerical difficulty arises when DAEs are solved with inconsistent initial values of dependent variables. It can cause the solution failures of many popular DAEs solvers. An initialization subroutine, DAEIS (Differential Algebraic Equations Initialization Subroutine), has been developed to handle this issue. In DAEIS, consistent initial values of dependent variables for index-1 DAEs are obtaine...
