Codo: Fundraising with Conditional Donations
summary
Codo implements a grammar for conditional donations, compiles conditions into a system of linear inequalities, and resolves them with linear program solver CPLEX; it forbids nonmonotonic conditions (negation, exact amounts) and uses an immediate, time‑oblivious resolution policy. A campus deployment funds veterinary care for kittens with a web front end; about one-third of donors use conditionals, conditional donors give ~3× more, and roughly 50% of conditionals remain unresolved after one week, showing feasibility but mixed short‑term payoff.
