Layer | Notation | Default | Parameter definition |
|---|---|---|---|
\(\omega\) | 0.75 | Probability of selection of the disease layer | |
n | 50 | Size of the square lattice graph, \(n^2\) is the total number of nodes in each layer | |
m | 1 | Number of edges to be attached from a new node in the Barabási–Albert network | |
Opinion | \(\upsilon ^{-}\) | 10% | Initial percentage of anti-vaccine opinions |
\(\upsilon ^{+}\) | 10% | Initial percentage of pro-vaccine opinions | |
\(\mathcal {O}_s\) | Rand | Placement strategy to assign supporters | |
\(\mathcal {O}_a\) | All | Opinion adoption method | |
\(\rho\) | 0.25 | Probability that the contrary opinion is adopted | |
Disease | \(\iota\) | 1% | Percentage of initial infection seeds |
\(\beta\) | 0.95 | Base probability that a susceptible gets infected provided infections in the neighborhood | |
\(\gamma\) | 0.25 | Probability that an infected recovers | |
\(\eta\) | 0.02 | Probability that a susceptible individual with neutral opinion gets vaccinated |
