A Journey in Creating a Digital Chess Master

Building a digital chess master has been a longstanding goal in the field of artificial intelligence (AI).

Chess, renowned for its complexity, has served as a litmus test for assessing whether a computer could match the strategic prowess of the human mind.

With approximately 1,040 possible legal moves in a game, the computational challenges are formidable.

The journey toward this goal began in 1957, when IBM engineer and mathematician Alex Bernstein crafted the first complete computer chess program.

Running on an IBM 704, this program could process 42,000 instructions per second with a memory of 70 kilobytes.

Progress continued in 1962, as a program developed at MIT on an IBM 7090 became the first to play chess credibly, evaluating 1,100 positions per second.

Throughout the 1970s, various programs managed to secure victories in amateur chess tournaments.

However, none could match the skill level of a grandmaster. The turning point came in the 1980s with the development of advanced chess-playing machines.

In 1985, a graduate student at Carnegie Mellon University named Feng-hsiung Hsu contributed to the creation of ChipTest, an advanced chess-playing machine.

This achievement marked a significant milestone, leading to the victory of the North American Computer Chess Championship in 1987.

Murray Campbell, a computer scientist with a profound interest in chess, joined forces with Hsu, culminating in the development of Deep Thought. This program became the first to defeat a grandmaster.

The journey toward creating a chess computer reached new heights in 1989, when both Hsu and Campbell were hired at IBM Research.

With the support of other IBM computer scientists like Joe Hoane, Jerry Brody, and C. J. Tan, they continued their work on enhancing the chess-playing computer, which was later renamed Deep Blue, paying homage to IBM’s moniker, Big Blue.

Deep Blue Design

Chess, the ultimate test of strategy and intellect, has long challenged computer scientists.

In the 20th century, machines began conquering games like checkers and tic-tac-toe, but chess remained a formidable foe.

In 1989, IBM’s supercomputer Deep Thought faced world champion Garry Kasparov but fell short.

Unfazed, IBM returned just a few years later with a new champion: Deep Blue.

Deep Blue stood tall in a tower-like structure, roughly 6.5 feet high, 3 feet wide, and 4 feet deep (2 meters x 1 meter x 1.2 meters). Its imposing presence housed custom Deep Blue chips within an IBM RS/6000 enclosure.

A stark contrast of black and blue defined the machine. The front door, where activity likely pulsed with hidden calculations, was jet black.

The base, a cool metallic blue, grounded the machine. Both front and back doors easily swung open on hinges, requiring a single key for access.

Deep Blue Software

Deep Blue’s evaluation function was initially developed with unspecified values for various parameters.

These parameters determined the relative value of different chessboard elements, such as king safety versus central control.

By analyzing thousands of master games, the researchers assigned values to these parameters, resulting in an evaluation function with 8,000 components optimized for various situations.

Deep Blue’s Knowledge Base

Deep Blue’s vast knowledge base included an opening book with over 4,000 positions and 700,000 grandmaster games, along with a comprehensive endgame database containing all five-piece and many six-piece endgames.

An additional database, called the “extended book,” summarized key strategic themes from Grandmaster games.

Leveraging its 200 million positions per second search capability, Deep Blue could efficiently consult the extended book to make informed opening move decisions.

Redesign for Second Match Preparations

To further refine Deep Blue’s opening strategy, grandmaster Joel Benjamin helped improve the program’s internal rules.

Additionally, grandmasters Miguel Illescas, John Fedorowicz, and Nick de Firmian contributed their expertise to the opening book.

Kasparov, seeking insights into Deep Blue’s playing style, requested access to its previous games.

IBM declined, and Kasparov resorted to studying popular PC chess games to familiarize himself with computer gameplay.

Deep Blue Hardware

Deep Blue employed specialized VLSI (Very Large Scale Integration) chips to parallelize the alpha-beta search algorithm, showcasing an example of symbolic AI in action.

The system’s formidable playing strength primarily stemmed from its sheer computational power.

It operated on an IBM RS/6000 SP Supercomputer, a parallel machine with 30 processors and custom-designed VLSI chips nicknamed “chess chips.”

These chess chips, specifically engineered to execute the chess-playing expert system, were made from CMOS (Complementary Metal-Oxide Semiconductor) technology.

The system also included FPGAs (Field-Programmable Gate Arrays) for potential adjustments to the chips, although this feature wasn’t used.

The entire setup was housed in two cabinets.

Each chess chip comprised four components: the move generator, the smart-move stack, the evaluation function, and the search control.

The move generator, a combinational logic circuit, acted as a miniature chessboard, capable of generating moves on an 8×8 grid.

Deep Blue’s chess-playing program was coded in the C programming language and operated on the AIX operating system.

It exhibited an impressive evaluation speed of 200 million positions per second, twice as fast as its 1996 predecessor.

In 1997, Deep Blue underwent further enhancements, propelling it to the 259th spot on the TOP500 list of the most powerful supercomputers.

It achieved a performance of 11.38 GFLOPS (GigaFLOPS) on the high-performance LINPACK benchmark, solidifying its computational prowess.

Deep Blue Computing Power

Deep Blue, an iconic chess computer by IBM, was renowned for its remarkable computing power.

At its core, Deep Blue leveraged 256 processors, enabling it to evaluate up to 200 million chess positions per second, a testament to its sophisticated design and optimization specifically for the game.

This phenomenal speed, translating to 11.38 billion floating-point operations per second (FLOPS), allowed Deep Blue to analyze and predict outcomes with a depth and accuracy far exceeding that of even the most skilled human players.

This computational prowess proved pivotal in 1997 when Deep Blue famously defeated the reigning world chess champion, Garry Kasparov, marking a significant milestone in Artificial Intelligence.

The Legacy of Deep Blue: IBM’s Masterpiece in Artificial Intelligence

After Deep Blue, a super-smart computer, won a game against Kasparov, a human chess champion, it was retired.

It’s now in a museum in Washington, D.C. But the company that made Deep Blue, called IBM, didn’t stop there.

They learned a lot from Deep Blue and used those lessons to make even more powerful computers, like Blue Gene and Watson.

Deep Blue was really special because it showed people how computers could be used to solve big, complicated problems.
