毕业设计&课设-MATLAB僵尸启示录模拟.zip

# zombie This is a more optimised version (**created by Kin Fai Franco Chan and Zakaria Achouri**) of the original MATLAB zombie apocalypse group project (https://github.com/UoMLegends/Zombie). This version uses vectorisation for movement increment, uses `knnsearch` for finding nearest enemy and preallocation for memory efficiency. ### To run the simulation, do the following steps: 1. save all the m files from this repository 2. execute `zombieBasic.m` using MATLAB 3. enjoy watching the zombie apocalypse simulation 4. execute `population.m` to plot the graphs of zombie population and human population versus time To simplify things, we modelled our zombie apocalypse based on a few simple behaviours of both zombies and humans. ### Basic behaviours of zombies and humans: * If human and zombie are **far away** from each other, they simply **move randomly** (Brownian motion). * If human and zombie are **relatively close** to each other, then the zombie would **chase** after the human, and the human would **run away**. * If a zombie is close to **multiple humans**, then the zombie would chase after the **closest** human. * If human and zombie are **very close** to each other, then they will **fight**. Sometimes the human wins the fight, which results in killing the zombie. And sometimes the zombie wins the fight, which results in turning the human into a zombie. ### Feel free to modify the parameters on `zombieBasic.m`: Parameters | Descriptions ---------- | ------------ `z0` | the initial zombie population `h0` | the initial human population `zSpeed` | zombie movement top speed `hSpeed` | human movement top speed `zSightRadius` | maximum distance a zombie can sense the presence of a human (for chase) `hSightRadius` | maximum distance a human can sense the presence of a zombie (for chase) `zAttackRadius` | maximum distance a zombie can attack from (for fight) `hAttackRadius` | maximum distance a human can attack from (for fight) `lim` | the length and the width of the arena (square arena) `pz`| the probability of zombie successfully converting a human to a zombie `ph`| the probability of human successfully killing a zombie
