Susceptibles at Time Step n +1 in the Discrete Multi Population SIS Model

Available identifiers

susceptibles in the discrete, multi-population SIS model

Defining Formula: $S_{n + 1}^{i} = S_{n}^{i} (1 - \sum_{k = 1}^{K} \frac{α_{i k} Δ t}{N^{i}} I_{n}^{k}) + γ_{i} Δ t I_{n}^{i}$
$I_{n}^{i}$ symbol represents Number of Infectious Individuals
$N^{i}$ symbol represents Total Population Size
$S_{n}^{i}$ symbol represents Number of Susceptible Individuals
$Δ t$ symbol represents Time Step
$α_{i k}$ symbol represents Contact Rate Between Two Groups
$γ_{i}$ symbol represents Relative Removal Rate
