Inspiration and genius--one and the same.

"The wise man in the storm prays God, not for safety from danger, but for deliverance from fear."
"Happiness is not a destination. It is a method of life."
"I believe God is managing affairs and that He doesn't need any advice from me. With God in charge, I believe everything will work out for the best in the end. So what is there to worry about."
"We shall not flag or fail. We shall go on to the end. We shall fight in France, we shall fight on the seas and the oceans, we shall fight with growing confidence and growing strength in the air, we shall defend our island, whatever the cost may be. We shall fight on the beaches, we shall fight on the landing grounds, we shall fight in the fields and in the streets, we shall fight in the hills; we shall never surrender."

Standard and Formatted Input / Output in C++

The C++ standard libraries provide an extensive set of input/output capabilities which we will see in subsequent chapters. This chapter will discuss very basic and most common I/O operations required for C++ programming. C++ I/O occurs in streams, which are sequences of bytes. If bytes flow from a device like a keyboard, a disk drive, or a network connection etc. to main memory, this is called input operation and if bytes flow from main memory to a device like a display screen, a printer, a disk drive, or a network connection, etc., this is called output operation . Standard Input and Output in C++ is done through the use of streams . Streams are generic places to send or receive data. In C++, I/O is done through classes and objects defined in the header file <iostream> . iostream stands for standard input-output stream. This header file contains definitions to objects like cin , cout , etc. /O Library Header Files There are...

Data Warehousing - An Overview

Anurag Information Technology (IT) has historically influenced organizational performance and competitive standing. The increasing processing power and sophistication of analytical tools and techniques have put the strong foundation for the product called data warehouse. There are a number of reasons that any organization should consider a data warehouse, which can be the critical tool for maximizing the organization’s investment in the information it has collected and stored throughout the enterprise. IT managers need to understand the rationale and benefits of data warehouses because they may need to design and implement, or procure this kingpin of business intelligence. The data warehouses are supposed to provide storage, functionality and responsiveness to queries beyond the capabilities of today's transaction-oriented databases. Also data warehouses are set to improve the data access performance of databases. Traditional databases balance the requirement of data access w...

Genotype Representation

Binary Representation This is one of the simplest and most widely used representation in GAs. In this type of representation the genotype consists of bit strings. For some problems when the solution space consists of Boolean decision variables – yes or no, the binary representation is natural. Take for example the 0/1 Knapsack Problem. If there are n items, we can represent a solution by a binary string of n elements, where the x th element tells whether the item x is picked (1) or not (0). For other problems, specifically those dealing with numbers, we can represent the numbers with their binary representation. The problem with this kind of encoding is that different bits have different significance and therefore mutation and crossover operators can have undesired consequences. This can be resolved to some extent by using Gray Coding, as a change in one bit does not have a massive effect on the solution. Real Valued Representation For problems where we want to define ...
