What is K center problem?
In graph theory, the metric k-center or metric facility location problem is a combinatorial optimization problem studied in theoretical computer science. Given n cities with specified distances, one wants to build k warehouses in different cities and minimize the maximum distance of a city to a warehouse.
What is approximation algorithm in DAA?
An Approximate Algorithm is a way of approach NP-COMPLETENESS for the optimization problem. This technique does not guarantee the best solution. The goal of an approximation algorithm is to come as close as possible to the optimum value in a reasonable amount of time which is at the most polynomial time.
Which is not a greedy algorithm?
Answer. Answer: Bellman-Ford implicitly tests all possible paths of length upto n-1 from the source node to every other node, so it is not greedy.
What is metric Center?
Description. Metric Business Center consists of 2 light industrial buildings totaling 47,900 square feet located in Austin, Texas. The buildings have 14′ clear heights, a total of 8 dock-high and 4 ground level doors, and 169 parking spaces. The property is close to Highway 183, MoPac Expressway.
What are the types of approximation algorithms?
Types of approximation algorithms. Fully polynomial-time approximation scheme. Constant factor. Knapsack problem.
What is vertex cover algorithm?
A vertex-cover of an undirected graph G = (V, E) is a subset of vertices V’ ⊆ V such that if edge (u, v) is an edge of G, then either u in V or v in V’ or both.
Is K vertex cover NP complete?
Since vertex cover is in both NP and NP Hard classes, it is NP Complete.
Is Dijkstra algorithm greedy?
Dijkstra Algorithm is a graph algorithm for finding the shortest path from a source node to all other nodes in a graph(single-source shortest path). It is a type of greedy algorithm. It only works on weighted graphs with positive weights.
What is matrix in BPO?
What does metrics mean in a call center? Call center metrics gauge the overall effectiveness of customer service teams. Many aspects of call centers use metrics to measure performance, agent productivity, and other activities that lead to increased customer satisfaction.
What is KPI in call center?
A KPI, or key performance indicator, is a metric that contact centers use to determine if they’re meeting business goals such as efficiency and delivering exceptional service.
What is A 1/2 approximation algorithm?
Algorithm 1 2-Approximation Algorithm for Minimum Vertex Cover Find a maximal matching M in G. Output the endpoints of edges in M: S = ⋃e∈M e. Claim 1 The output of algorithm 1 is feasible. Proof: We prove this by contradiction: suppose there exists an edge e = (u, v) such that u,v /∈ S.
What is approximation algorithm example?
A simple example of an approximation algorithm is one for the minimum vertex cover problem, where the goal is to choose the smallest set of vertices such that every edge in the input graph contains at least one chosen vertex.
