Motivate Build Status

Setup

Install rust using rustup

Running Motivate

Configuration

config/parameters.yaml

---
total_years: the number of years the simulation runs for
number_of_people: the number of people in the simulation
number_of_simulations: the number of simulations to run in parallel
social_connectivity: how connected an agent is to its social network
subculture_connectivity: how connected an agent is to its subculture
neighbourhood_connectivity: how connected an agent is to its neighbourhood
number_of_social_network_links: the minimum number of links an agent should have in its social network
number_of_neighbour_links: the minimum number of neighbours an agent should be influenced by
days_in_habit_average: the number of days that account for approximately 86% of the habit average
distributions: this should not be changed

  change_in_number_of_bikes: 10000 <- An increase (or decrease) in the number of bikes
  change_in_number_of_cars: -100 <- An increase (or decrease) in the number of cars

Running the simulation

On the first run of the simulation run cargo run --release -- --generate, so that social networks are generated.

Afterwards in the root of the repository run cargo run --release.

Generating Documentation

Documentation can be generated by running cargo rustdoc -- --document-private-items

Notes

As specified in .cargo/config the generated executable will target the cpu it is compiled on, therefore binaries created on one system, may not execute on other systems, even if they run the same operating system. To remove this requirement remove -C target_cpu=native from .cargo/config, however this could have an impact on performance.
