(CNN) -- Lots of normal people would pay $23 for a book.

But $23.seven million (plus $3.99 shipping) for a scientific book about flies!?

This unthinkable sticker price for "The Making of a Fly" on Amazon.com was spotted on April 18 at Michael Eisen,######## oakley, an evolutionary biologist and blogger.

The market-blind book listing was no the result of uncontrollable claim for Peter Lawrence's "prestigious work in developmental biology," Eisen writes.

Instead, it appears it was sparked by a robot price war.

"What's magnetic about all this is either the seemingly infinite possibilities for both muddle and mischief," writes Eisen, who works at the University of California at Berkeley and blogs at a site cried "it is NOT junk." "It seems impossible that we stumbled onto the only instance of this kind of ascent pricing spiral."

Eisen saw the automaton price war from April eight to 18 and reckoned that two booksellers were automatically adjusting their prices against each other.

One equation kept setting the price of the first book at 1.27059 times the price of the second book, according to Eisen's thinking, which is posted in detail on his blog.

The additional equation automatically set its price at 0.9983 times the price of the other book. So the prices of the two books escalated in tandem into the millions, with the second book always selling for slightly fewer than the first. (Not that that materials much when you're selling a book about flies for millions of dollars).

The episode highlights a little-known truth about e-commerce sites such as Amazon: Often, folk don't establish and update prices; computer algorithms do.

Individual booksellers on Amazon and other sites disburse third-party companies for algorithm services that automatically update prices. Some of these computer programs purportedly work quite well, obtaining sellers up to 60% more sales because they underbid the tournament automatically and again.

The conveniences are clear: If you're managing dozens of sale items on Amazon or eBay, it's tough if necessary impossible to reserve up with all of them.

"If you have more than 100 items, then it's impossible for you to manually converge on the price," said Victor Rosenman, CEO of a company called Feedvisor, which sells algorithm services to people who use Amazon.

"It's pretty many like the stock commute. What you look there is the prices changing all the time -- but they never change drastically. Sometimes it's a dollar here a dollar there -- perhaps $10. For a book, it probably would be pennies."

These algorithms vary widely in quality, although, as the Amazon case shows.

Sellers easily can shirk the million-dollar-book position whether they set amount ceilings and layers on their pricing algorithms, so namely the competitive commanding shuts off at a certain dollar jot,######## oakley sunglasses sale, Rosenman said.

"It's favor you put on the gas and didn't have the handbrake," he said. "This is a very elementary mistake. So I am very, very wondered this entity occurred at all."

Some of these algorithm services give clients control over their equations, letting them edit them for they go. That doesn't always work out well, Rosenman said.

His enterprise knobs all of this for clients, yet charges a hefty fee, catching 1% to 5% of the seller's profits and charging every month fees of $500 to a few thousand greenbacks a month, relying above the size of the contract, he said.

Robot-adjusted prices may change a few times one hour or a few periods a daytime, he said, depending on how competitive a price warfare becomes.

These algorithms try to detect if they're working opposition other computers or peoples and then they modify tactics therefore, he said.

They too take other elements into consideration,discount sunglasses, including how well the seller is rated by Amazon consumers. A seller with a great pathway record may be able to sell books for a slightly higher price because of his or her reputation.

Eisen, who premier blogged about the overpriced book, writes that "alas, celebrity afterward noticed" the brutal price of "The Making of a Fly." On April 19, he says, the price of the book plummeted from extra than $23 million to $106.23.

On Monday p.m., the fashionable book was listed at $976.98, and Eisen thinks the price is escalating repeatedly.

Neither Amazon nor either of the individual writing sellers answered to requests for annotate from CNN.

If nothing another,######## oakleys sunglasses outlet, Eisen writes, the situation earned the fly-book's author some bragging rights: "Peter Lawrence can immediately comfortably boast that one of the biggest and maximum adored companies on Earth amounted his large book at $23,698,655.93 (plus $3.99 shipping)."
