Network Design

Networks are represented as weighted directed graphs.

Example CSV:

day,source,target,weight 0,A,A,0.99 0,A,B,0.01 0,B,B,0.995 0,B,A,0.005

Each row specifies the contribution of infections in the source patch to the force of infection in the target patch. The day column selects when the weights take effect; use 0 for a static network.

Weights

Weights are used exactly as provided — they are not auto-normalized. The force of infection for patch i is Σⱼ Wᵢⱼ · Iⱼ/Nⱼ, so a common convention is to make each source patch’s outgoing weights sum to 1 (including a self-loop source == target for within-patch transmission), as in the example above.
