+**ConfOpt** is significantly better than plain old random search, but it also beats established tools like **Optuna** or traditional **Gaussian Processes**!
+
+The above benchmark considers neural architecture search on complex image recognition datasets (JAHS-201) and neural network tuning on tabular classification datasets (LCBench-L).
+
+For a fuller analysis of caveats and benchmarking results, refer to the latest methodological paper.
