Summary: Review Request: coin-or-Couenne -Couenne, an exact
solver for nonconvex MINLPs
Product: Fedora
Version: rawhide
Component: Package Review
Severity: medium
Priority: medium
Reporter: paulo.cesar.pereira.de.andrade(a)gmail.com
Spec URL: http://pcpa.fedorapeople.org/coin-or/coin-or-Couenne.spec
SRPM URL:
http://pcpa.fedorapeople.org/coin-or/coin-or-Couenne-0.4.3-1.fc19.src.rpm
Description: Couenne (Convex Over and Under ENvelopes for Nonlinear Estimation)
is a
branch&bound algorithm to solve Mixed-Integer Nonlinear Programming (MINLP)
problems of the form:
min f0(x,y)
fi(x,y) <= 0 i=1,2..., m
x in Rn, y in Zp
where all fi(x,y) are, in general, nonlinear functions.
Couenne aims at finding global optima of nonconvex MINLPs. It implements
linearization, bound reduction, and branching methods within a
branch-and-bound framework. Its main components are:
* an expression library;
* separation of linearization cuts;
* branching rules;
* bound tightening methods.

Summary: Review Request: coin-or-Bonmin - Basic Open-source
Nonlinear Mixed INteger programming
Product: Fedora
Version: rawhide
Component: Package Review
Severity: medium
Priority: medium
Reporter: paulo.cesar.pereira.de.andrade(a)gmail.com
Spec URL: http://pcpa.fedorapeople.org/coin-or/coin-or-Bonmin.spec
SRPM URL:
http://pcpa.fedorapeople.org/coin-or/coin-or-Bonmin-1.6.0-3.fc19.src.rpm
Description: Bonmin (Basic Open-source Nonlinear Mixed INteger programming) is
an
experimental open-source C++ code for solving general MINLP (Mixed Integer
NonLinear Programming) problems of the form:
min f(x)
s.t. g_L <= g(x) <= g_U
x_L <= x <= x_U
x_i in Z for all i in I and,
x_i in R for all i not in I.
where f(x): R^n --> R, g(x): R^n --> R^m are twice continuously differentiable
functions and I is a subset of {1,..,n}.
Bonmin features several algorithms
* B-BB is a NLP-based branch-and-bound algorithm,
* B-OA is an outer-approximation decomposition algorithm,
* B-QG is an implementation of Quesada and Grossmann's branch-and-cut
algorithm,
* B-Hyb is a hybrid outer-approximation based branch-and-cut algorithm.
The algorithms in Bonmin are exact when the functions f and g are convex;
in the case where f or g or both are non-convex they are heuristics.

Summary: Review Request: coin-or-FlopC++ - Algebraic modelling
language
Product: Fedora
Version: rawhide
Component: Package Review
Severity: medium
Priority: medium
Reporter: paulo.cesar.pereira.de.andrade(a)gmail.com
Spec URL: http://pcpa.fedorapeople.org/coin-or/coin-or-FlopC++.spec
SRPM URL:
http://pcpa.fedorapeople.org/coin-or/coin-or-FlopC++-1.1.2-3.fc19.src.rpm
Description: An open source algebraic modelling language implemented as a C++
class
library.
Using FLOPC++, linear optimization models can be specified in a declarative
style, similar to algebraic modelling languages such as GAMS and AMPL,
within a C++ program. As a result the traditional strengths of algebraic
modelling languages are preserved, while embedding linear optimization
models in software applications is facilitated.
FLOPC++ can be used as a substitute for traditional modelling languages,
when modelling linear optimization problems, but its principal strength
lies in the fact that the modelling facilities are combined with a
powerful general purpose programming language. This combination is
essential for implementing efficient algorithms (using linear optimization
for subproblems), integrating optimization models in user applications, etc.

Integer Programming
Product: Fedora
Version: rawhide
Component: Package Review
Severity: medium
Priority: medium
Reporter: paulo.cesar.pereira.de.andrade(a)gmail.com
Spec URL: http://pcpa.fedorapeople.org/coin-or/coin-or-Dip.spec
SRPM URL:
http://pcpa.fedorapeople.org/coin-or/coin-or-Dip-0.83.2-3.fc19.src.rpm
Description: DIP (Decomposition for Integer Programming) is an open-source
extensible
software framework for implementing decomposition-based bounding algorithms
for use in solving large-scale discrete optimization problems. The framework
provides a simple API for experimenting with various decomposition-based
algorithms, such as Dantzig-Wolfe decomposition, Lagrangian relaxation,
and various cutting plane methods. Given a compact formulation and a
relaxation, the framework takes care of all algorithmic details associated
with implementing any of a wide range of decomposition-based algorithms,
such as branch and cut, branch and price, branch and cut and price,
subgradient-based Lagrangian relaxation, branch and relax and cut, and
decompose and cut. The user can specify customizations, such as methods
for generating valid inequalities and branching, in terms of the variables
of the compact formulation, without having to worry about the details of
any required reformulations.

Differentiation of C++ Algorithms

Description: CppAD: A Package for Differentiation of C++ Algorithms
We refer to the step by step conversion from an algorithm that computes
function values to an algorithm that computes derivative values as
Algorithmic Differentiation (often referred to as Automatic Differentiation.)
Given a C++ algorithm that computes function values, CppAD generates an
algorithm that computes its derivative values. A brief introduction to
Algorithmic Differentiation can be found in
http://en.wikipedia.org/wiki/Automatic_differentiation. The
web site http://www.autodiff.org/ is dedicated to research about, and
promoting the use, of AD.
