assignment problem

assignment problem : The assignment problem is one of the fundamental combinatorial optimization problems in the branch of optimization or operations research in mathematics. It consists of finding a maximum weight matching in a weighted bipartite graph. In its most general form, the problem is as follows: If the numbers of agents and tasks are equal and the total cost of the assignment for all tasks is equal to the sum of the costs for each agent (or the sum of the costs for each task, which is the same thing in this case), then the problem is called the Linear assignment problem. Commonly, when speaking of the Assignment problem without any additional qualification, then the Linear assignment problem is meant. The Hungarian algorithm is one of many algorithms that have been devised that solve the linear assignment problem within time bounded by a polynomial expression of the number of agents. The assignment problem is a special case of the transportation problem, which is a specia....   More from Wikipedia

assignment problem : In applied mathematics, the maximum general assignment problem is a problem in combinatorial optimization. This problem is a generalization of the assignment problem in which both tasks and agents have a size. Moreover, the size of each task might vary from one agent to the other.

Question : An instructor wishes to see whether the variation in scores of the 23 students in her class is less than the variance of the population. The variance of the class is 198. is there enough evidence to support the claim that the variation of the students is less than the population variance ( 2 = 225 ) at = .05? a.State the hypotheses and identify the claim. b.Find the critical value c.Determine the appropriate statistical test(s) and compute for the test value if necessary. d.Make t..

Answer : a) Ho: 2 = 225 Ha: 2 < 225 b) The test statistic for this hypothesis follows the chi-square distribution. This is a left tail test, so the critical value is: X^2 = 12.338 (alpha .05, 22 df) c) The test statistic for this hypothesis follows the chi-square distribution and is given by: ((n-1*(s^2))/ 2 =(22*198)/225 =19.36 d) Since the test statistic (19.36) is greater than the critical value (12.338) we fail to reject the null hypothesis. e) At the .05 significance level, we conclude that there is not sufficient evidence to claim that the variance of the class scores is differs significantly from the population variance of 225...   More from Yahoo Answers

Question : Any way I have to write about my daily journey (school day) in 120 words. I have and I'm not sure if it's right so don't type rude remarks also I haven't used a transaltor. Le matin je me l ve toujours cinq heures puis je me lave et me brosse mes dents. Je prend mon petit d jeuner a six heures moins le quart. Je mange normalement un oeuf et bois du lait. Je m habille puis je quitte la maison et je vais mon cole sept heures en voiture. Les cours commencent a huit heures moins..

Answer : Good work, X! And congratulations on not using a translator. IMHO, they are not to be trusted. Here are the corrections I would make to your text (changing "dix heures" to "vingt-deux heures" at the end is just for the sake of consistency with the rest of your narration). Don't be stingy with commas; punctuation always helps. Also, don't forget the grave accent on the preposition " ." Le matin je me l ve toujours cinq heures, puis je me lave [or: je fais ma toilette] et je me brosse les dents. Je prends mon petit d jeuner six heures moins quart. Je mange normalement un uf et je bois du lait. Je m habille, puis je quitte la maison et je pars pour l' cole sept heures, en voiture. Les cours commencent huit heures moins quart et finissent treize heures et quart mais nous avons une recr ation onze heures moins vingt. Apr s tre rentr e [or: Apr s mon retour] la maison, je prends mon d jeuner puis je me repose pendant une heure. quinze heures je ....   More from Yahoo Answers
