# This example runs the same scenario repeatedly, each time cancelling a
|
|
# different number of trips uniformly at random. The eventual goal is to
|
|
# quantify how many trips need to be cancelled to substantially speed up
|
|
# remaining ones.
|
|
#
|
|
# Before running this script, start the API server:
|
|
#
|
|
# > cargo run --release --bin headless -- --port=1234 --alerts=silence
|
|
#
|
|
# You may need to install https://requests.readthedocs.io
|
|
# Keep this script formatted with autopep8 -i
