What is co$-$operative machine learning in multi$-$agent environment? In such case how two different types of agents can learn together selectively? Design multi$-$agent system with cooperative learning for medicine delivery in a hospital. In this case prescribed medicines to be delivered to a particular patient$$s room within half an hour. What will be function of different agents in this case? What will be PEAS for these agents? How $$Best first search$$ algorithm can be used in this case. Can we use combination of Manhattan and Euclidean distance in this case to determine heuristic values? Clearly define possible heuristic function and discuss its admissibility. Provide detailed diagram, analysis and pseudo code.
