(a) Design an algorithm that reveals some secret integer number from the set {1, 2, ... , n} by guessing random numbers within the given range until the secret number has been guessed. Numbers should be replaced after being guessed such that it is possible to guess 2 and then 2 again, assuming 2 is in the given range. The algorithm should return both the secret number as well as the number of guesses taken. (b) If possible, calculate the...

In the project I am working right now, we have some python and some C# code. At some point, I call from python a subprocess which starts a C# executable. This C# code returns an error code, which has to be understood on the python side and a readable report has to be created. This means, both sides "must speak the same language". So, at the end I have to handle a mapping {error codes: readable explanation} (normally we implement...

Consider n indivisible objects with distinct types i = 1, 2, 3,…, n. We are given positive integer weights W = {w1,w2...wn} and positive integer prices V = {v1,v2...vn} for the objects and a knapsack of weight capacity (m). Our problem is to find the maximum profit possible by including a subset of the objects into the knapsack with total weight of at most m. This form of the 0/1 Knapsack Problem can be solved by a Decrease and Conquer...

2. We distribute n points uniformly and independently on the circumference of a circle, and want to compute the probability that there is a semicircle that contain all of them. (In other words, the probability that there is a line through the center of the circle such that all n points lie on the same side of this line.) Let E be the event that such a semicircle exists. Denote by Pi, P2, ..., Pn the random points, and by...
