....Fortran 77 [11] In an object oriented programming environment, it is preferable to use an implementation which is able to handle arbitrarily defined graphs. In this case, no information about the incidence graph has to be stored. Such subroutines are for example provided by the C library LEDA [17]. The complete Algorithm 7 runs in O(n nz) time, where nz is the number of nonzero in H. The permutation algorithm proposed in [4, Alg. 3.4] is a special case of Algorithm 7. It is a structure preserving version of the permutation algorithm from [21] that is used, e.g. in LAPACK [2] for ....

....X. Biconnected components form a proper partition of the graph edges. It is standard to compute a mapping from each edge in a graph to a unique number of its biconnected component. For a graph with n vertices and m edges this can be done in time O(n m) using depth rst search (see e.g. [11]) Now we can compute the set of free root variables in linear time. We use a control bit for each biconnected component. When processing a root 11 candidate X, we can use the bit to check for each child Y whether the number of the edge (X; Y ) has already occurred at another child of X. Since we ....

....must use a finite initial temperature. 4. Experiments In order to evaluate our algorithm and to compare it to other classical simulated annealing algorithms, we designed and implemented a general local search optimisation platform. This platform is written in C using the LEDA library [9]. A graphical interface written in Tcl Tk is also provided. Source code is available upon request to the first author. 24 E. Poupaert and Y. Deville Simulated Annealing with estimated temperature This platform is designed such that local search algorithms and optimisation problems are ....

....was designed to close that gap. LEDA SM is a prototype library that supports I O efficient data structures that can be used in many applications. To circumvent the rewriting of efficient algorithms and data structures for in core problems, LEDA SM is designed as an extension of the LEDA library [MN95] and hence requires to be used together with LEDA. LEDA SM provides a sizable collection of data types and algorithms in a form which allows them to be used by non experts. LEDA SM gives a pre4 cise and readable specification for each of the data types and algorithms. The specifications are short ....

....Our algorithm uses only standard algorithmic building blocks such as the computation of strongly connected components, Dijkstra s algorithm, or the Bellman Ford algorithm, which are well studied and easy to implement. An implementation of our algorithm will become part of the LEDA software package [8] in the near future.
