ndflow
Network flow in the nth-dimension!
Usage
First install like this:
npm install ndflow
Then use it as follows:
require("ndflow")(
[[0,1,2], [1,2,3]],
[1, 1],
[[0,1], [1,3], [3,2], [2,0]],
[1,1,1,1],
[1,1])
require("ndflow")(cells, capacities, boundary_cells, boundary_weights, cost)
Solves for the flow from the boundary cells that minimizes the cost. This is the same thing as solving the linear program:
Minimize cost(flow)
Subject to D(flow) = boundary_cells * boundary_weights
0 <= flow <= capacities
In the case where the cell complex is one dimensional, this is the same as solving minimum cost network flow for a given capacity. Binary searching on the scale of the capacities lets one compute a maximum/min-cost flow.
