In order to solve a computational problem, its solution must be specified in terms of asequence of computational steps, each of which may be performed by a human or a digital computer. If you want to solve the computational problem with a computer, you shouldlearn how to program. The task of developing programs for the solution of computationalproblems is referred to as programming. Computer programming is the process of planningand creating a sequence of steps for a computer to follow. In general, this process will helpus resolve a problem, which is either too tedious or difficult to work out otherwise. Soprogramming is breaking a task down into small steps.
Programming is sometimes contrasted with coding. Coding generally refers to thewriting of programs for given program specification, while programming includes the task of preparing the program specification as well as that of writing the program. The text of aprogram is sometimes referred to as code, and lines of program text are referred to as lines ofcode, especially in the case of machine-language programs. The term coder is used todescribe a person engaged exclusively in implementing program specifications prepared byothers. What ' s actually involved in programming - the actual process of writing programs? Here' s a quick overview of the process:
• Write a program.
• Compile the program.
• Run the program.
• Debug the program.
• Repeat the whole process until the program is finished.

Since computers can handle large amount of data rapidly and efficiently, categorize, process, and report information for a variety of business operations, they, in fact, have a virtually unlimited capacity for producing business data. However, computers can't think, their role in business is limited to those areas in which they can process information more efficiently and effectively than human being. At the administrative level, managers decide how computers and humans can be used most effectively to perform. a particular business task.
Computers have become an integral part of day-to-day business transactions as well as analytic tools for long range planning, research, and development. Even a small business can utilize computers by either purchasing a small unit known as a minicomputer, leasing one, or by timesharing. In a timesharing system, each user is regularly scheduled for time to use the computer system. A wide variety of businesses and individuals participate in timesharing computer system.
By performing data processing tasks such as accounting and billing, computers are playing an increasingly important role in businesses. Currently, business are developing overall management information systems in which computers function as essential tools in solving problem and decisionmaking at all administrative levels.

In recent years, computer experts, particularly those specializing in artificial intelligence, have felt the same fascination and frustration. Programming other board games has been a relative snap. Even chess has succumbed to the power of the processor. Five years ago, a chess-playing computer called Deep Blue not only beat but thoroughly humbled Garry Kasparov, the world champion at that time. That is because chess, while highly complex, can be reduced to a matter of brute force computation. Go is different. Deceptively easy to learn, either for a computer or a human, it is a game of such depth and complexity that it can take years for a person to become a strong player. To date, no computer has been able to achieve a skill level beyond that of the casual player.
The game is played on a board divided into a grid of 19 horizontal and 19 vertical lines. Black and white pieces called stones are placed one at a time on the grid's intersections. The object is to acquire and defend territory by surrounding it with stones. Programmers working on Go see it as more accurate than chess in reflecting the ways the human mind works. The challenge of programming a computer to mimic that process goes to the core of artificial intelligence, which involves the study of learning and decision-making, strategic thinking, knowledge representation, pattern recognition and perhaps most intriguingly, intuition.
Along with intuition, pattern recognition is a large part of the game. While computers are good at crunching numbers, people are naturally good at matching patterns. Humans can recognize an acquaintance at a glance, even from the back.
Daniel Bump, a mathematics professor at Stanford, works on a program called GNU Go in his spare time.
"You can very quickly look at a chess game and see if there's some major issue," he said. But to make a decision in Go, he said, players must learn to combine their pattern-matching abilities with the logic and knowledge they have accrued in years of playing.
"Part of the challenge has to do with processing speed. The typical chess program can evaluate about 300,000 positions in a second, and Deep Blue was able to evaluate some 200 million positions in a second. By mid-game, most Go programs can evaluate only a couple of dozen positions each second," said Anders Kierulf, who wrote a program called SmartGo.
In the course of a chess game, a player has an average of 25 to 35 moves available. In Go, on the other hand, a player can choose from an average of 240 moves. A Go-playing computer would need about 30,000 years to look as far ahead as Deep Blue can with chess in three seconds, said Michael Reiss, a computer scientist in London. But the obstacles go deeper than processing power. Not only do Go programs have trouble evaluating positions quickly; they have trouble evaluating them correctly. Nonetheless, the allure of computer Go increases as the difficulties it poses encourage programmers to advance basic work in artificial intelligence.
For that reason, Fotland said, "writing a strong Go program will teach us more about making computers think like people than writing a strong chess program. "
What does the sentence "Programming other board games has been a relative snap. " (Paragraph 2) indicate?
A.Programming other board games has been relatively easy.
B.Programming other board games has been relatively difficult.
C.Programming other board games has been relatively complicated.
D.Programming other board games has been relatively predictable.
