Design a MapReduce algorithm that computes the sum of amultiset. The input is represented by pairs (x,m) where x is anelement of the multiset and m is its multiplicity, i.e., the number oftimes it is included in the set.For example, the multiset [3, 1, 2, 2, 3, 3, 2, 1, 3] is represented bythe pairs [(1,2),(2,3),(3,4)], and the desired output is 20.What is the map function? What is the reduce function? Describeany considerations you would take into account.
Given an abstraction of the City Tube Map where each node represents the city’s attraction, plan the trip for the tourist to visit. Start from node 1 that is their hotel, a group of tourists wants to visit all places. However, due to the time limitation, they can only visit each attraction once. To find the best order of places to visit, genetic algorithm can be used to derive the best possible solutions.

I need to implement a python code for Q learning and SARSA method. My example involves a cliff walking experiment where the rewards are -1 except for the region marked as cliff if the agent steps there the reward is -100 and the agent is sent back to the start. The values used are alpha = 0.1, y or gamma = 1 and the e- greedy action is 0.1. After using these values on both algorithm the results needs to be shown by using matplot. The graph should have episodes in the x axis and sum of rewards during episode on the y axis. It needs to be smoothed out by averaging over 10 runs and, plotting moving average over last 10 episodes. This needs to be done in python using numpy and panda but I'm not allowed to use gym library or any other library.
Suppose a candidate solution p, where p is a phenotype consisting of 4 vertices. Suppose that minimum fitness occurs when no pair of vertices in p are connected, and maximum fitness occurs when all pairs of vertices in p are connected. Write a pseudocode on how to calculate the fitness F of p.
Use of Matching for Edge ColouringEdges in a matching can share the same colour since matching in a graph is defined as the collection of non-adjacent edges. As a result, we can create an algorithm based on this idea using the below stages. 1. Input: G = (V, E)2. Output: Minimal edge coloring of G3. color ← 04. while G = ∅$5. find maximal matching M of G6. color all M vertices with color7. G ← G − M8. color ← color + 1implementation of Python

Create an SP client that analyses the edge-weighted digraph's edges in relation to a specified pair of vertices, s and t: Create a V-by-V boolean matrix where each item in row v and column w is true for each v and w if the edge v->w is an edge in the edge-weighted digraphs whose weight can be raised without increasing the length of the shortest path from v to w, and false otherwise.
