A simple pandemic simulation with customizable parameters written in Rust, rendered with Raylib.

Customisable parameters:

• INFECTION_RADIUS - Radius around infected person where normal person is susceptible to infection
• INFECTION_RATE - Probability that normal person will get infected when within infection radius
• NUMBALLS - Number of people
• INITIAL_INFECTED_POPULATION - Number of people infected at start of simualtion
• MAXSPEED - Maximum possible speed that people move around at (speeds and start locations are random)
• BASE_RECOVERY_TIME - Base time for recovery
• RECOVERY_TIME_RANGE - recovery_time = BASE_RECOVERY_TIME + rand(-RECOVERY_TIME_RANGE, RECOVERY_TIME_RANGE), accounts for natural variation in recovery times.
• FATALITY_RATE - Percentage of people that would die after recovery_time has elapsed. Remaining will recover.

Instructions:

1. git clone https://github.com/gursi26/pandemic_simulation.git
2. cd pandemic_simulation
3. cargo run

Dependecies:

• raylib-rs

TODOs

• Use grid rendering system for better performance with higher number of objects
• Other, more optimised collision detection methods
• Include phenomena like
  • Social distancing
  • Lockdown with frequent trips to a central location (like a grocery store)
  • Separate communities with travel between them
  • Quarantine zones for infected patients
  • Asymptomatic cases
  • Fatality rate
  • Recovery rate
  • Virus mutating into a stronger variant (more contagious or more deadly)
