  • LON-NPP-demo.R script for LON models creation, visualisation and metric calculation. Number Partitioning Problem (NPP) instances are used as case study. By G. Ochoa in EvoCOP 2017. LON datasets are here provided to be used with the script:
    • – LON data with N = 10, k = 0.4 before the phase transition, single funnel structure.
    • – LON data with N = 10, k = 1.0 after the phase transition, multi-funnel structure.
    • – LON dataset containing instances of size 10, 15 and 20, and with values of k from 0.4 to 1.2 in steps of 0.1.
  • Code in Python for an example Iterated Local Search code instrumented to record the LON data through sampling of multiple runs. Code in R to parse the sampled data and build a LON. By N. Veerapen
  • Code in C++ to exhaustively extract LONs of the Quadratic Assignment Problem (QAP). By S. Verel in CEC 2010.
  • Code in Java for efficient generation of LON graphs on non-neutral landscapes. By J. E. Fieldsend¬†and featured in GECCO 2018.
