Nash equilibrium

Posted by in categories: economics, entertainment

J. V. Neumann, Zur Theorie der Gesellschaftsspiele, 1928. Proved the existence of equilibrium in 2 players’ zero-sum games.

The birth of game theory.


The modern concept of Nash equilibrium is instead defined in terms of mixed strategies, where players choose a probability distribution over possible pure strategies (which might put 100% of the probability on one pure strategy; such pure strategies are a subset of mixed strategies). The concept of a mixed-strategy equilibrium was introduced by John von Neumann and Oskar Morgenstern in their 1944 book The Theory of Games and Economic Behavior, but their analysis was restricted to the special case of zero-sum games. They showed that a mixed-strategy Nash equilibrium will exist for any zero-sum game with a finite set of actions.[13] The contribution of Nash in his 1951 article “Non-Cooperative Games” was to define a mixed-strategy Nash equilibrium for any game with a finite set of actions and prove that at least one (mixed-strategy) Nash equilibrium must exist in such a game. The key to Nash’s ability to prove existence far more generally than von Neumann lay in his definition of equilibrium. According to Nash, “an equilibrium point is an n-tuple such that each player’s mixed strategy maximizes his payoff if the strategies of the others are held fixed. Thus each player’s strategy is optimal against those of the others.” Putting the problem in this framework allowed Nash to employ the Kakutani fixed-point theorem in his 1950 paper to prove existence of equilibria. His 1951 paper used the simpler Brouwer fixed-point theorem for the same purpose.[14]

Moore’s Law for Everything

Posted by in categories: biotech/medical, economics, law, policy, robotics/AI

Fascinating vision/plan by the one and only Sam Altman of how to update our economic systems to benefit everyone in the context of rapidly accelerating technological change.


My work at OpenAI reminds me every day about the magnitude of the socioeconomic change that is coming sooner than most people believe. Software that can think and learn will do more and more of the work that people now do. Even more power will shift from labor to capital. If public policy doesn’t adapt accordingly, most people will end up worse off than they are today.

We need to design a system that embraces this technological future and taxes the assets that will make up most of the value in that world–companies and land–in order to fairly distribute some of the coming wealth. Doing so can make the society of the future much less divisive and enable everyone to participate in its gains.

Voice Assistants Learn the Art of Small Talk

Posted by in categories: business, economics, education, habitats

Voice assistants have already made significant strides in areas such as smart home integration, educational settings and business applications. However, their current capabilities are limited by a lack of robust reasoning and planning abilities.

In fact, just 7.8% of consumers believe voice technology is as smart and reliable as a real person today, according to the PYMNTS Intelligence report “ How Consumers Want to Live in the Voice Economy.”

Hackers stole 340,000 Social Security numbers from government consulting firm

Posted by in categories: cybercrime/malcode, economics, government

GMA provides economic and litigation support to companies and U.S. government agencies, including the U.S. Department of Justice, bringing civil litigation. According to its data breach notice, GMA told affected individuals that their personal information “was obtained by the U.S. Department of Justice (“DOJ”) as part of a civil litigation matter” supported by GMA.

The reasons and target of the DOJ’s civil litigation are not known. A spokesperson for the Justice Department did not respond to a request for comment.

GMA said that individuals notified of the data breach are “not the subject of this investigation or the associated litigation matters,” and that the cyberattack “does not impact your current Medicare benefits or coverage.”

It Is Time To Take Intel Seriously As A Chip Foundry

Posted by in categories: computing, economics, finance, government, security

The third proof point is both the increase in manufacturing capacity investment and the change in how that investment will be managed. With the interest in governments to secure future semiconductor manufacturing for both supply security and economic growth, Mr. Gelsinger went on a spending spree with investment in expanding capacity in Oregon, Ireland, and Israel, as well as six new fabs in Arizona, Ohio, and Germany. Most of the initial investment was made without the promise of government grants, such as the US Chips Act. However, Intel has now secured more than $50B from US and European government incentives, customer commitments starting with its first five customers on the 18A process node, and its financial partners. Intel has also secured an additional $11B loan from the US government and a 25% investment tax credit.

In addition to it’s own investment in fab capacity, Intel is partnering with Tower Semiconductor and UMC, two foundries with long and successful histories. Tower will be investing in new equipment to be installed in Intel’s New Mexico facility for analog products, and UMC will partner with Intel to leverage three of the older Arizona fabs and process nodes, starting with the 12nm, to support applications like industrial IoT, mobile, communications infrastructure, and networking.

The second side of this investment is how current and future capacity will be used. As strictly an IDM, Intel has historically capitalized on its investments in the physical fab structures by retrofitting the fabs after three process nodes, on average. While this allowed for the reuse of the structures and infrastructure, it eliminated support for older process nodes, which are important for many foundry customers. According to Omdia Research, less than 3% of all semiconductors are produced on the latest process nodes. As a result, Intel is shifting from retrofitting fabs for new process nodes to maintaining fabs to support extended life cycles of older process nodes, as shown in the chart below. This requires additional capacity for newer process nodes.

Virtual colonoscopy lets you skip the scope. Here’s what to know about the colorectal cancer screening Mark Cuban says saves time and money

Posted by in categories: biotech/medical, computing, economics, health

Whereas traditional colonoscopy involves snaking a camera called a colonoscope through your colon and rectum, a CT colonography, or virtual colonoscopy, consists of X-rays and a computer creating 3D images of these organs.

If you’re between the ages of 45 and 85, you should have a colorectal cancer screening routine in place, per the American Cancer Society (ACS). But a colonoscopy —in which your doctor uses a special camera to look inside your colon and rectum in search of abnormal growths called polyps —isn’t the only option to take charge of your gastrointestinal health.

You can choose from noninvasive screening methods: computed tomography (CT) colonography and/or a stool-based test. Billionaire entrepreneur and Shark Tank investor Mark Cuban tells Fortune he enjoys the relatively low cost and simplicity of the former, also called virtual colonoscopy. In short, it’s an X-ray exam that doesn’t require sedation or anesthesia.

Hydrogen to power Japan’s new passenger jet by 2035

Posted by in categories: economics, energy, transportation

As AFP reports, in a meeting with industry experts, an economy ministry official outlined a target completion date of post-2035. To achieve this ambitious goal, a significant investment of five trillion yen ($33 billion) will be allocated over the next decade, fueling research and development of the new passenger plane.

This latest endeavor seeks to establish Japan as a leader in passenger aircraft production – a position it hasn’t held in over half a century. Building on the challenges that Mitsubishi Heavy Industries (MHI) encountered, which canceled its long-delayed passenger jet project in 2023, the new public-private consortium strongly emphasizes clean energy.

8 million UK jobs at risk from AI

Posted by in categories: economics, employment, mobile phones, robotics/AI

A new report warns of potentially major disruption to UK employment from the coming wave of AI. An estimated 11% of tasks are already exposed to current AI, a figure that could rise to 59% during a second wave. But there could also be opportunities for economic growth.

From the discovery and use of fire in the Stone Age, through to the handheld smartphones of today, technology has improved our living standards and is the foundation of modern society. Yet unmanaged technological change comes with risks and disruptions. The current wave of technology including generative AI – described by some as the “Fourth Industrial Revolution” – promises transformative benefits, while at the same time bringing potential disruption through its impact on wage inequality, wealth inequality, and job displacement.
