From failed candidate to chief scientist

Chapter 184 Mersenne Primes Report

"Next, we invite Professor Jiang Fanjun from the Mathematics Research Center of Dongshan University to come on stage to give a special report on the 15 new Mersenne primes they discovered."

Under the introduction of Curtis Cooper, Jiang Fanjun walked onto the stage calmly.

Below, a group of Mersenne prime number enthusiasts who came from all over the world looked at Jiang Fanjun who walked on the stage with different expressions.

Some people glared at Jiang Fanjun, some were curious about Jiang Fanjun, and there were even a few who were envious of Jiang Fanjun.

Jiang Fanjun ignored these glances and stood on the stage with a smile.

"Entrusted by Teacher Lin Mo, I am very happy to give this report on behalf of the Mathematics Research Center of Dongshan University!"

"About our newly discovered 15 Mersenne primes..."

"The reason why we were able to discover these Mersenne primes in a short period of time is related to the new algorithm we used..."

"Our new algorithm for Mersenne primes..."

"The above is our optimization and improvement of the Mersenne prime number calculation algorithm. According to our calculations, the improved algorithm can greatly save computing power. The CPU usage is reduced by 80% compared with before, and the computing efficiency is improved by one percent compared with before. Ten thousand times."

"Some people may question my words, but I think the results in front of me can explain everything better. As you can see, the 15 new Mersenne primes on the big screen behind me are the new Mersenne primes we used. The algorithm took 3 days to calculate and discover.”

Jiang Fanjun stood on the stage and talked confidently.

All the fans of Mersenne prime numbers below were speechless.

Some people suddenly realized, some felt lost, some looked terrified, and some were full of doubts.

optimization?

It turns out that an optimized algorithm was used?
What did we hear?An optimization algorithm that improves efficiency by 10000 times?

Are you kidding me?How can there be algorithm optimization, which can increase the efficiency by [-] times, are you optimizing?
You are a liar!This is obviously a new algorithm, okay?

Even though Jiang Fanjun had just briefly introduced the idea of ​​the optimization algorithm and the basic operation logic, some people still didn't want to believe it.

It's like, everyone is still using 286, but you directly go to the Core Quad Core. How can people accept this?
Everyone only had one thought in their mind, they had met a cheater!
Everyone honestly calculated using 286. Whoever can calculate it is lucky. But the result is that your Dongshan University Mathematics Research Center is better. It directly opens the plug-in. Does it talk about military ethics? Is there any academic fairness?

Immediately, someone jumped up in the audience.

"So, Professor Jiang, are you admitting that the new Mersenne prime number you discovered was not discovered using Prime95?"

"If you have to say that, all I can say is, yes."

Hearing Jiang Fanjun's answer, the person who asked the question immediately had a look of satisfaction on his face.

"Mr. Cooper, you have heard that the 15 Mersenne primes they discovered were not discovered using Prime95. I propose to disqualify them from discovery. They are violating the spirit of fairness and have no respect for GIMPS. I think they The Mersenne prime numbers discovered are ineffective!" As the man finished speaking, there were bursts of echoes from the audience.

Jiang Fanjun was speechless, his eyes swept over the people in the audience who were clamoring to disqualify the Mason prime number he had discovered, and then turned his attention to Curtis Cooper.

Curtis Cooper felt the pressure in Jiang Fanjun's eyes and quickly came on stage.

"Please be quiet! First of all, I want to declare one thing here, that is, the GIMPS official recognizes the contribution of the Dongshan University Mathematics Research Center to the discovery of Mersenne primes, and recognizes the 15 Mersenne primes they discovered after verification. Confirmed valid!"

Curtis Cooper settled the matter with one sentence and blocked the discussion below.

Uncertainty is not enough. Before this report meeting, Curtis Cooper had a preliminary communication with Jiang Fanjun. After understanding that Jiang Fanjun was able to discover so many new Mersenne primes in a short period of time, it was because After using the new algorithm, Curtis-Cooper came up with the idea of ​​​​this new algorithm.

He is a person who really loves the Mersenne primes. Otherwise, he would not do the management work of GIMPS for free and devote all his energy to the search for the Mersenne primes.

Therefore, after hearing that there is a more efficient and faster calculation algorithm, Curtis-Cooper can't wait to update this algorithm to Prime95, so that more people can participate in it and discover more Mersenne prime numbers.

Curtis Cooper proposed on the spot that Jiang Fanjun could authorize this new algorithm to GIMPS for use by GIMPS.

Regarding this, Lin Mo discussed this matter with Jiang Fanjun before he came. This new algorithm can be provided to GIMPS. The reason why he agreed to Curtis Cooper to hold this report meeting was that Lin Mo saved the algorithm. The idea of ​​selling to GIMPS.

When Curtis Cooper heard Jiang Fanjun say that the algorithm could be provided to GIMPS, he was extremely happy. However, after hearing Jiang Fanjun's conditions, Curtis Cooper's heart dropped.

No way, GIMPS can't afford the high algorithm fees. GIMPS is not a for-profit organization. Its operating funds still rely on donations raised by enthusiastic enthusiasts. Therefore, for the US$100 million fee reported by Jiang Fanjun, Ke Thies-Cooper was devastated.

For this reason, Jiang Fanjun even called back specifically to communicate with Lin Mo.

After discussion between the two, it was finally decided that the algorithm can be provided to GIMPS free of charge, but it is only the right to use it. GIMPS cannot obtain the complete algorithm and underlying code. Jiang Fanjun will encrypt the algorithm and update it to Prime95 so that Prime95 can use it. New algorithm.

The reason for this is to ensure that the algorithm and underlying code are not leaked. After all, this algorithm can not only be used to calculate Mersenne prime numbers. In fact, this new algorithm improved by Lin Mo can greatly reduce the number of multiplication problems. The algorithm has a very wide range of applications and is by no means limited to the calculation of Mersenne prime numbers. Lin Mo also pointed to this algorithm to earn research and development funds.

Of course, although they don't charge money, GIMPS doesn't have to do anything, which is too cheap for them.

GIMPS must announce to the outside world that Prime95 uses a new algorithm from the Dongshan University Mathematics Research Center, and publicly announce that through the new algorithm, the calculation efficiency of Mersenne prime numbers has increased by 10000 times.

To put it bluntly, I asked GIMPS to advertise for Dongshan University Mathematics Research Center.

Being able to use the new algorithm without spending money has already made Curtis Cooper overjoyed and happy. As for advertising, isn't this the right thing to do?Even if Jiang Fanjun didn't mention it, Curtis Cooper planned to help advertise.

Ever since, the two sides hit it off and settled the matter quickly.

So at this time, seeing Jiang Fanjun being targeted, Curtis Cooper immediately stepped forward to help Jiang Fanjun clear his name, fearing that Jiang Fanjun would be dissatisfied and disrupt the update of Prime95.
