Greedy algorithm exam questions
Webthat each vertex is part of exactly one edge. Give a polynomial time algorithm that takes a tree on 2n vertices as input and nds a perfect matching in the tree, if there is one. Solution: We give a greedy algorithm. Actually our algorithm will work whenever the input graph is acyclic. (a) Find a vertex of degree 1 in the graph. http://www.cs.ecu.edu/karl/3650/sum04/solution2.html

WebNov 19, 2024 · Let's look at the various approaches for solving this problem. Earliest Start Time First i.e. select the interval that has the earliest start time. Take a look at the following example that breaks this solution. This solution failed because there could be an interval that starts very early but that is very long. WebDec 21, 2024 · A greedy algorithm is an algorithmic paradigm that follows the problem-solving heuristic of making the locally optimal choice at each stage with the hope of finding a global optimum. Figure: Greedy…

WebJan 1, 2015 · A greedy algorithm also has to make choices, and does so on the basis of local optimizations that may not be optimal globally. But it is expected to succeed anyway and does not have to backtrack: the price of greediness is that the "cost" (however defined) of the result obtained by the algorithm may be higher than the cost of the optimal solution.
