NAME
    COOOL LIBRARY

SYNOPSIS
    #include <coool.hh>

DESCRIPTION
    COOOL 
    Welcome to the COOOL library version 1.1. COOOL stands 
    for Center for Wave Phenomena Object Oriented 
    Optimization Library. The Center for Wave Phenomena 
    is a research group at the Department of Geophysics, 
    Colorado School of Mines. Among others some of the 
    research activities developed at CWP are geophysical
    data inversion, anisotropic seismic wave propagation, 
    high performance computing and so on.
    
    This library was developed with the purpose to provide the
    user with a reasonable set of optimization procedures
    to tackle linear and non linear optimization problems. 
    Some of those algorithms resort to the derivatives of 
    the objective function (the functional that you intend to 
    minimize), however some of them are derivative-free 
    procedures. We tried to be creative in the communication 
    protocol between the COOOL library algorithms and the user-
    -coded objective function. The EXPECT mechanism, a freely 
    available software written by Don Libe suited, very well
    for this purpose. Besides the algorithms we provide
    C++ classes to manipulate vectors and (sparse or dense)
    matrices that can be useful for scientific software 
    development. 

DESCRIPTION
    COOOL 
    The following is a brief description of the optimization
    algorithms that are available in the present version of 
    the COOOL library:
    
    Linear system solvers: 
    	Conjugate Gradient for Least Squares (CGLS)
    Interative Reweighted Least Squares (Irls)
    
    Non linear optimization tools:
    Derivative-free:
    	Powell's method (Powell)
    	Simplex (Simplex)
    Derivative-based:
    	Conjugate Gradient (CG) with Polak-Ribiere and 
    	Fletcher-Reeves	step computation procedures
    	available
    
    Line searches:
    Derivative-free:
    	Brent's algorithm (BrentLineSearch)
    Derivative-based:
    	Cubic line search (CubicLineSearch)
    
    Vector and Matrix manipulation classes:
    take a look at Vector.hh (Vector) and Matrix.hh (Matrix)
    
    Man pages are available to easier the usage of the COOOL 
    library. To get detailed information about the algorithms 
    listed above type man followed by whatever is between 
    parentheses (It is not case sensitive!).
    
    For information on how to install the COOOL library and how
    to run the demos look at the README file. For detailed 
    information on the internal structure of the library and 
    about the optimization algorithms check the post script file 
    available via WWW - Netscape at:
    http://vita.mines.edu:3857/jscales
    or via anonymous FTP to landau.mines.edu. 
    "cd" to the directory pub/coool and transfer the file
    coool.ps.gz. You should use gzip to uncompress this file. 

DISCLAIMER
    The COOOL library is a free software. You can distribute 
    copies to whoever you want and in any amount you wish. 
    Since you got the source code you can also modify the
    library to fit better into your own purposes. We appreciate 
    if the headers that identify the authors are kept in the 
    source code.
    The COOOL library has bugs. The ones we detected we went 
    ahead and fixed, but we strongly appreciate any bug reports 
    that you send us. Please use the following E-mail address: 
           [e-mail].
    We will fix them (almost) immediatly and send a newer version 
    to you. But as in any disclaimer the following annoying 
    message should be present. So here it goes:
    
    There are no guarantees, explicit or implicit, made by the 
    Center for Wave Phenomena, the Colorado School of Mines, or 
    any member of the aforesaid organizations, past, present, or 
    future, regarding the accuracy, safety, usefulness, or any 
    other quality or aspect of this software.
    
    Thanks for using COOOL.
