APEX-CUTE 4.1 Now Available.
The Agricultural Policy Environmental eXtender – auto-Calibration and UncerTainty Estimator (APEX-CUTE) is coded in Python. The current version includes sensitivity analysis (SA) and the dynamically dimensioned search (DDS) algorithm (Tolson and Shoemaker, 2007) for APEX auto-calibration. Three methods are provided in APEX-CUTE for SA: method of Morris (or EE), Sobol’, and Fourier amplitude sensitivity testing (FAST). As with any SA and/or auto-calibration tools, users should conduct necessary checks for model input and initial runs before conducting SA and/or auto-calibration to make sure that the basic APEX input and setup are correct. APEX-CUTE interacts with APEX by modifying APEX input files with candidate solution, running APEX, evaluating model output by calculating performance statistics, perturbing current best solution to generate candidate solution, and iteratively repeating the process until maximum number of objective function evaluations completed.
