Changelog

All notable changes to this project will be documented in this file. The version scheme adopted is %YYYY%MM%DD where Y is the year, M the month and D the day of the release.

Not realeased

  • Add seed as an optional option in rrwg.conf to be used by the pseudo-random number generator.

20220831

  • Normalize each column in the rrwg.dat file by the walks instead by vertices. The sum of the columns with the same walk must be one. See #7 and #8.
  • Rename rrwg.conf to rrwg.conf.example. This allows the use of configuration file in the project directory that is not overwritten by the project file.

20220830

  • Fix approximation of the results in rrwg.dat.
  • R script file is not generated anymore.
  • Normalization of number of visits was done in the code.

20220826

  • Add partitions option in the simulation where a walk can go to a complete subgraph from the original graph.
  • Increase the details in the log file.
  • Put the walk label in the header of data file rrwg.dat.
  • The program generates a R script to plot the results.
  • The program opens the browser to view the plot generated.
  • Put a epsilon parameter in the power function.
  • All parameters are set in a file called rrwg.conf.
  • Eliminate all flags.
  • Remove the matplotlib part.
  • Test and purge CWEB.

20220624

  • Rewrite the entire program separating the funcionalities into modules.

  • Use pyinstaller to generate a sigle executable file.

  • Simplify the program arguments and the initial assumptions, no input file is required.

20220225

Added

  • Create class Writer to handle IO operations, mostly write.
  • Add a static method to create a graph called create_graph.
  • Create the __str__ method to the class Graph.
  • Write the data in float format.
  • Put limits in the plot for y axis.
  • Improve program arguments handling.
  • Add an example of execution command line in the README.

20220224

Added

  • The Random Repelling Walks on Graphs simulation was ported from C to Python. The user may pass as argument the number of walks to simulate, the repelling function to be used and the repelling coefficient called alpha. The program generates a data file containing the path of each walker.
