NAME

       algotutor - an interactive program for observing the intermediate steps of algorithms.

SYNOPSIS

       algotutor [OPTION] ... DATA ...

DESCRIPTION

       algotutor is an interactive program for observing the intermediate steps of algorithms.
       The target audience is computer science students and/or anyone who studies algorithms
       and/or data structures. One can create data files in plain text format (actually perl
       anonymous hashes, but one need not care) and let algotutor runs through some predefined
       algorithm. Then one can step backward and forward through the execution sequence of the
       algorithm at different levels of details. It requires perl-Tk.

       DATA is the input data. For the dynamic programming algorithms such as lcs and matc,
       please see the respective entries in the following list; for other algorithms, it is the
       file name containing the actual input data.

OPTIONS

       -a ALGO
           Runs the algorithm ALGO. Currently ALGO can be one of:

           bst operations on binary search trees
           rbt operations on red-black trees (remove() is not implemented yet)
           heap operations on heaps -- the remove operation on a heap always removes the top
           element regardless of the argument
           sbs stack-based search on graphs, a variant of depth first search
           bfs breadth first search on graphs
           prim Prim's minimal spanning tree on graphs
           dijk Dijkstra's single-source shortest path on graphs
           flwa Floyd-Warshall's all-pair shortest path on graphs (very, very slow)
           dom 2-dimensional point domination
           graham Graham's scan for convex hull
           lcs longest common subsequence -- it requires two strings as the command line
           arguments. For example, "algotutor -a lcs AGCTATACGATGACT GTCAGTATAGTCATATG"
           matc optimal matrix chain multiplication -- it requires an alternating sequence of
           integers and matrix names as the command line arguments. For example, "algotutor -a
           matc 32 A 35 B 24 C 30 D 36 E 25 F 40 G 34 H 35" means finding the optimal
           multiplication sequence of the chain of matrices: A of size 32 by 35, B of size 35 by
           24, ... H of size 34 by 35.
       -s VERTEX
           Use VERTEX as the starting vertex (for sbs, bfs, prim, and dijk)

       -i STEP
           Display step STEP as the initial image.

       -d FILENAME
           Dump the picture into FILENAME as a ps file and exit immediately without going into
           interactive mode.
