Results of 1,000 iterations of a constrained stochastic economic optimization algorithm applied to government costs associated with bovine tuberculosis detection in cow-calf herds. The constrained optimizer was not allowed to prefer control strategies that led to herds falsely clearing quarantine. Costs were calculated using the national average for values that vary by region. Level (color) indicates frequency of visit by the optimization algorithm, with the optimal solution being that with a level closest to 1.
