Devise an algorithm that generates an access control matrix A for any given history matrix H of the Chinese Wall model. A significant portion of the grade for this problem involves your justification of your algorithm.
Consider using mandatory access controls an compartments to implement an ORCON control. Assume that there are k different organizations. Organization i will produce n(i,j) documents to be shared with organization j.
a) How many compartments are needed to allow any organization to share a document with any other organization? Show your work.
b) Now assume that organization i will need to share nm(i,i1,...,im) with organizations i¬1,...,im. How many compartments will be needed? Show your work.
Describe an algorithm that finds a maximum feasible flow in G. Denote by MF(|V|, |E|) the worst-case running time of an ordinary maximum flow algorithm.
Suggest a lazy version of the eager decision tree learning algorithm ID3. What are the advantages and disadvantages of your lazy algorithm compared to the eager algorithm.
The recent discovery of the following fragment of uncommented procedural C code in the Sunlab has caused a big scandal. What is the worst-case time complexity of foo(a,1,N,k), and for which inputsdoes it occur?
Their priorities are 2, 3, 1, 5 and 4, respectively, with 1 being the highest priority. Specify the order in which processes execute and determine the mean process turnaround time for each of the scheduling algorithms.
Design an algorithm that will receive two integer items from a terminal operator, and display to the screen their sum, difference, product and quotient.
Consider a simple symmetric encryption algorithm as follows:Is it a problem if the first block of input happens to be the same as the key? Explain why?
Explain a sorting algorithm which is optimal with respect to this cost model and uses O(n) space. That is, time used by algorithm should exactly match lower bound
You should build enough new roads such that if City A was reachable from City B via some old roads, City A must be reachable from City B via some new roads.
Using any programming language to implement iterative version of algorithm HEAPIFY. Show your algorithm by running it on the array that contain your name characters.
n vehicles occupy squares (1, 1) through ( n , 1) (i.e., the bottom row) of an n × n grid. The vehicles must be moved to the top row but in reverse order
