An honest coin is tossed 1600 times, and it lands heads 520 times. The question of interest is are we playing with an honest coin? (1) What statisticwould choose to determine the answer? (2) What is your conclusion? Show how you came to this conclusion? (3) What is your confidence in your conclusion? Elaborate on all your answers. Solution 1) The probability of heads/tails using a fair coin would be (1/2) i.e, a count of 800 heads/tails in 1600 trials would determine that its a honest coin. 2) since the probability of the heads is (520/1600), it is not a honest coin. 3) 100% confident, for more details: http://en.wikipedia.org/wiki/Fair_coin.

An Euler cycle in a directed graph is a cycle in which every edge is visited exactly once. Design an algorithm to test whether a given direct graph has an Euler cycle or not, and if so, find such a cycle. Solution ALGORITHM Given a starting vertex , the v0algorithm will first find a cycle C starting and ending at v0 such that C contains all edges going into and out of v0. This can be performed by a walk in the graph. As we discover vertices in cycle C, we will create a linked list which contains vertices in order and such that the list begins and ends in vertex v0. We set the current painter to the head of the list. We now traverse the list by moving our pointer \"current\" to successive vertices until we and a vertex which has an outgoing edge which has not been discovered. (If we reach the end of the list, then we have already found the Eule cycle ). Suppose we find the vertex, vi, that has an undiscovered outgoing edge. We then take a walk beginning and ending at vi such that all undiscovered edges containing vi are contained in the walk. We insert our new linked list into old linked list in place of vi and more \"current\" to the new neighbor pointed to the first node containing vi. We continue this process until we search the final node of the linked list, and the list will then contains an Euler cycle Running Time of Euler cycle The algorithm traverse each edge at most twice, first in a walk and second while traversing the list to find vertices with outgoing edges. Therefore, the total running time of the algorithm is O(|E|)..

Wizards are very useful for creating a good user experience. In all businesses, interactive sessions are most beneficial. To improve the user experience, wizards in Odoo provide an interactive session. For creating wizards, we can use transient models or abstract models. This gives features of a model class except the data storing. Transient and abstract models have permanent database persistence. For them, database tables are made, and the records in such tables are kept until they are specifically erased.
