Our Jan-2019 Challenge asks you to help a cyber police to specify rules that identify if a robot is friendly or unfriendly. The rules can be expressed in terms of any features you can see in robots, such as the shape of the head, the color of the jacket, the height, the color of their antennas, what they are holding in their hands, whether they are smiling or not, etc. When manually determined rules failed,  the police started to look at the integrated machine learning and business rules approach. If you can help, please send your solution to  DecisionManagementCommunity@gmail.com.
