[FK88] Consider the distributed tree search scheme in which processors are allocated to separate parts of the search tree dynamically. Initially, all the processors are assigned to the root. When the root node is expanded (by one of the processors assigned to it), disjoint subsets of processors at the root are assigned to each successor, in accordance with a selected processor-allocation strategy. One possible processorallocation strategy is to divide the processors equally among ancestor nodes. This process continues until there is only one processor assigned to a node. At this time, the processor searches the tree rooted at the node sequentially. If a processor finishes searching the search tree rooted at the node, it is reassigned to its parent node. If the parent node has other successor nodes still being explored, then this processor is allocated to one of them. Otherwise, the processor is assigned to its parent. This process continues until the entire tree is searched. Comment on the performance and scalability of this scheme.
A Boolean matrix has the parity property when each row and each column has an even sum, i.e. contains an even number of bits which are set. Here's a 4 x 4 matrix which has the parity property:
Composite and multi-valued attributes can be nested to any number of levels. Suppose we want to design an attribute (one attribute) for a STUDENT entity type to keep track of previous college education.
Question 1:Summarize the issue that you have chosen. Question 2: Express your own opinion of, or position on, the issue that you have chosen. Question 3: Identify two to three (2-3) human and technological protective measures that you would use as ..
Write all possible topological orders for the vertices in this new graph.
The Lorenz curve is a relative measure of income. This becomes obvious when one compares Lorenz curves between nations. The after-transfer income distribution is the Lorenz curve closest to the diagonal line. Since transfers favor the poor, they cau..
Determine the access time when there is cache miss? Suppose that cache waits until line has been fetched from main memory and then re-executes for hit.
Develop, document and design an Enhanced Entity Relationship (EER) model for this situation. You are working for country club with thousands of members. You have been tasked with designing a database to keep track of the members and their guests.
Write a C++ class derived from Graph Interface, as given in Listing 20-1. Use an adjacency matrix to represent the graph.
Read its documentation and experiment with it. Measure how fast it is able to encrypt and decrypt data. Are these two rates the same? Try to compare these timing results using different key sizes; for example, compare single-DES with triple-DES.

In addition to continuations that represent the "normal" continued execution of a program, we can use continuations in place of exceptions. For example, consider the following function f that raises an exception when the argument x is too small:
