# Makefile for the project.

# Provides targets for building, running, benchmarking, testing, and visualization.
|

#
|
|
# Main commands:
|
|
# make run run the simulation, producing a CSV file
|
|
# containing pedestrian states at each iteration
|
|
# make video generate a video of the simulation
|
|
# make run-bench run benchmark measurements
|
|
# make test run all unit tests
|
|
#
|
|
# Default parameters can be overridden from the shell, as follows:
|
|
# (parameters can be provided selectively and in any order)
|

# make run N_P=<num_ped> N_ITER=<num_iter> CSV=<out.csv>
