To visualize solutions, you can use Python and tools as follows:

1. Create folder track_finding
2. Create folders data, results and visualization in folder track_finding
3. Download the hits_selected.zip (Ignore if you downloaded) and extract to folder data
4. Download the solution files (Ignore if you downloaded) and extract to folder results
5. Download the visualize_solution.py file in folder visualization (You must to install matplotlib and pandas)

To be sure the directory structure is correct like that:

• track_finding
  • data
    • hits_selected
      • V_9_N_10_E_100_P_1.csv
      • ....
  • results
    • V_9_N_10_E_100_P_1_P_1_B_250_D_15
      • C_BLP
        • solution.json
      • A_QUBM
        • solution.json
      • ....
  • visualization
    • visualize_solution.py

  Now, you can choose the solution file path corresponding to the methods you want to show.
