This is a Master final project program simulating the Vicsek model and two new Vicsek variation using levy flights and burst-and-coasts dynamics.

The program can run three different models depending on the input mode:

• Mode 0: Classic Vicsek model
• Mode 1: Lévy behaviour model
• Mode 2: Burst-and-coast model

And different measures and options can be done in the input file. This file includes the following parameters:

• Output directory: directory where to write all output data
• Status filename: filename of the 'status' file (if None, an automatic name is set)
• Mode: desired model (0/1/2)
• Noise Scan mode: take noise values list from the file 'noise_values.dat' (True/False)
• Noise value: desired noise valu if Scan_mode is False
• Lévy alpha parameter: characteristic power-law parameter for the Lévy model
• Mean flight: mean flight parameter for Vicsek Model and Lévy model
• burst amplitude: Delta-v for the burst-and-coast model
• N_measures: number of measurements in every iteration
• N_steps: time-steps between consecutives measurements
• N_reset: time-steps to reset the system (thermalazing)
• N_iterations: number of total iteration of the simulation
• N_GNF: the number of boxes to use in the GNF computation
• Polarization: temporal evolution of the global order (True/False)
• GNF: Giant Nuber Fluctuations measurement (True/False)
• Configuration: Positions of all particles through the simulation to visualize them later (True/False)
• Speed: temporal evolution of the global group speed (True/False)
• ignore_last_config: do not use last scenario from last simulation to start the new one (True/False)
• L: desired system size
• Density: desired system density
• Random seed

Python file presents a fast analysis of data in one output directory. To use the visualization in video use the file visualyzer.py changing the proper directory in its 7th line.
