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
• INITIALINFECTEDPOPULATION - Number of people infected at start of simualtion
• MAXSPEED - Maximum possible speed that people move around at (speeds and start locations are random)
• BASERECOVERYTIME - Base time for recovery
• RECOVERYTIMERANGE - recoverytime = BASERECOVERYTIME + rand(-RECOVERYTIMERANGE, RECOVERYTIME_RANGE), accounts for natural variation in recovery times.
• FATALITYRATE - Percentage of people that would die after recoverytime has elapsed. Remaining will recover.

Instructions:

• git clone https://github.com/gursi26/pandemic_simulation.git
• cd pandemic_simulation
• 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 - [X] Fatality rate - [X] Recovery rate - [ ] Virus mutating into a stronger variant (more contagious or more deadly)
