mcl-algorithm 08-157 (Default branch)
The MCL (Markov Cluster Algorithm) is a fast andscalable cluster algorithm for graphs based onstochastic flow. The flow process employed by thealgorithm is mathematically sound andintrinsically tied to cluster structure in graphs,which is revealed as the imprint left by theprocess. The threaded implementation has handledgraphs of up to one million nodes within hours,and is widely used in the field of protein familyanalysis. It comes with a wide range of siblingutilities for handling and analyzing graphs,matrices, and clusterings.License: GNU General Public License (GPL)Changes:
The mcl suite is moving towards a wider focus ongeneral purpose large scale graph analysis, withthe emphasis, besides clustering, on basic graphand clustering measures and transformations. Theprogram mcxarray can now transform tabular geneexpression data into graph input. The clm utilitycomputes clustering coefficients, diameter andeccentricity, and betweenness centrality. Manyfixes and improvements were made throughout.Image

NAME

       crypt_unix - traditional UNIX crypt algorithm

DESCRIPTION

       The  crypt_unix algorithm is the traditional UNIX crypt algorithm. It is not considered sufficiently secure for current systems and is pro-
       vided for backwards compatibility. The crypt_sunmd5(5), crypt_bsdmd5(5), or crypt_bsdbf(5) algorithm should be used instead.

       The algorithm identifier for policy.conf(4) is __unix__. There is no entry in crypt.conf(4) for this algorithm.

       The crypt_unix algorithm is internal to libc and provides the string encoding function used by crypt(3C) when the first	character  of  the
       salt is not a "$".

       This algorithm is based on a one-way encryption algorithm with variations intended (among other things) to frustrate use of hardware imple-
       mentations of a key search.  Only the first eight characters of the key passed to crypt() are  used  with  this	algorithm;  the  rest  are
       silently  ignored.  The salt is a two-character string chosen from the set [a-zA-Z0-9./].  This string is used to perturb the hashing algo-
       rithm in one of 4096 different ways.

       The maximum password length for crypt_unix is 8 characters.

USAGE

       The return value of the crypt_unix algorithm might not be portable among standard-conforming systems. See standards(5).
