Available identifiers

susceptibles in the discrete, multi-population SI model

Defining Formula: $S_{n + 1}^{i} = S_{n}^{i} (1 - \sum_{k = 1}^{K} \frac{α_{i k} Δ t}{N^{i}} I_{n}^{k})$
$I_{n}^{i}$ 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
