# Josephus Problem formula

The original Josephus problem consisted of a circle of 41 men with every third man killed (,), illustrated above, where the outer number indicates the order in which a given man is killed. In order for the lives of the last two men to be spared, they must be placed at positions 31 (last) and 16 (second-to-last) The process stops when one number remains. It is required to find the last number. This task was set by Flavius Josephus in the 1st century (though in a somewhat narrower formulation: for k = 2). This problem can be solved by modeling the procedure Der jüdische Historiker Flavius Josephus (37-95) berichtete davon, dass er mit 40 anderen Juden vor den Römern in einen Keller flüchtete. Um dem Feind nicht in die Hände zu geraten, beschlossen sie, sich gegenseitig umzubringen - nur Josephus war dagegen. Deshalb schlug er vor, sich in einem Kreis aufzustellen und jeweils jeden Dritten auf der Stelle zu erschlagen. Da er sich geschickt in den Kreis stellte, blieb er als Letzter übrig und überlebte. In Auswertung der. The problem has following recursive structure. josephus(n, k) = (josephus(n - 1, k) + k-1) % n + 1 josephus(1, k) = 1. After the first person (kth from beginning) is killed, n-1 persons are left. So we call josephus(n - 1, k) to get the position with n-1 persons. But the position returned by josephus(n - 1, k) will consider the position starting from k%n + 1. So, we must make adjustments to the position returned by josephus(n - 1, k)

Description (from Rosetta Code) Josephus problem is a math puzzle with a grim description: prisoners are standing on a circle, sequentially numbered from to . An executioner walks along the circle, starting from prisoner , removing every -th prisoner and killing him. As the process goes on, the circle becomes smaller and smaller, until only one. In computer science and mathematics, the Josephus problem (or Josephus permutation) is a theoretical problem related to a certain counting-out game. People are standing in a circle waiting to be executed. Counting begins at a specified point in the circle and proceeds around the circle in a specified direction

Take the number of people (41 in Josephus's case including himself). Find the closest power of 2 lesser than that number. It is 32 in this case; Now, write 41 in terms of 32 plus some number. Here, 41 = 32 + 9; Take this 9. Multiply by 2 and add 1. You get 19; Hence, Josephus should stand in position 19 to avoid being killed. In Computer Programmin def josephus(n,k): l = list(range(1,n+1)) josephus_permutation = [] m=0 while len(l)>0: for i in range(k): p = (i+m) % len(l) if p == len(l)-1: m=0 else: m=p josephus_permutation.append(l[p]) del l[p] return josephus_permutatio REKURSIONEN UND DAS JOSEPHUS-PROBLEM3 i7!2i+ 1 { also z.B. 1 7!3;2 7!5;3 7!7;::: { anwenden.

The Josephus Problem asks where to start taking out every kth person in the circle consisted of n people, such that you are the last survivor. The following recursive formula is given: f (1, k) = 1, f (n, k) = ((f (n − 1, k) + k − 1) mod n) + 1. But this is not enough explanation, so I don't get where does it come from The Josephus Problem 11 The Josephus Problem To find the general formula, we can use the fact that any number can be written as a power of 2 plus a remainder (r). Note: after r steps, whoever's turn it is will be the winner as we will be left with a power of 2. When there are 5 soldiers, the winning position is 3 An alternating elimination Josephus problem has a deep connection to the powers of two, a connection reflected in the formula we derived to find the winning spot. The formula requires a few simple calculations, and is a function of the number of participants n: find the largest power of two in n, subtract it from n, double the result, and add 1. The person in that spot will be the winner The mathematical formula to the problem is provided in the video and can be summarised as follows. If n = p + L, where n is the total number of people and p (referred to as 2 a in the video) is the greatest power of 2 that is less than n, then the winning position is 2L + 1

We analyze an enumeration associated with the Josephus problem by applying a Fourier transform to a multivariate genera- ting function.

Further, Josephus appears to have had the habit of referring to Jewish ethical responsibility as piety and justice. 5 If this is indeed the case, as Mason affirms, then it would appear that Jospehus' only real concern is to present John as a very ethical Jewish person—thus he inserts his formula, piety and justice—not necessarily to stress the details of his message Find the solution of the Josephus problem when 2005 people are involved using (a) the cyclic shift and (b) the formula Apply quickselect to find the median of the list of numbers 9. 12, 5, 17, 20, 30, 8.

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): We give explicit non-recursive formulas to compute the Josephus-numbers j(n; 2; i) and j(n; 3; i) and explicit upper and lower bounds for j(n; k; i) (where k 4) which differ by 2k \Gamma 2 (for k = 4 the bounds are even better). Furthermore we present a new fast algorithm to calculate j(n; k; i) which is based upon. Thus, the formula would put the start of his reign in Tishri 39 and the end of his reign in Nov/Dec 36, and the calculation would be: 39t BC + AD 69t - 1 (no zero year) = 107 years. Note that Josephus does not move on to Herod's acts as king until after he treats Antigonus's death. So, at least for Josephus, Herod's reign does not begin.
