Application of Markov chain in infectious disease dynamics model and combined with Brownian motion optimization

• SEIR.py, SIR.py, SI.py

  Simulation of classic infectious disease dynamics model.

• epidemic_data.xlsx

  Infectious disease data were recorded.

• COVID-19_in_HuBei_SEIR.py, COVID-19_in_HuBei_SIR.py

  The previous data are simulated using SEIR model and SIR model.

• improved_SEIR.py

  Optimized SEIR model for the above data for prediction.

• SEIRwithBrown.py

  Combining the optimization model of Brownian motion and adding an isolation mechanism.
