AI beat a human at poker

09.03.2017

Matej Moravcik of the University of Alberta and other members of an international team of scientists from Canadian and Czech academic institutions have developed an artificial intelligence system that can beat a human in the most difficult version of poker known as Texas Hold'em. This is a complex game, the number of possible moves in it reaches 10160.

A feature of poker in terms of AI work is unequal access to information. For example, in the case of chess, all players see the same pieces on the board, while in a card game the distribution of information at each moment of time is asymmetrical - only the player himself knows his set of cards.

DeepStack - as the new system is called - beat 10 out of 11 and professional players in more than 3000 games. Strictly speaking, he beat the 11th, only the advantage is not big enough. Before each move, the AI recalculated the strategy of the game, subject to restrictions on the depth of calculations and types of moves, which allowed the number of possible moves in each round to be limited to about 107. (Traditionally, AI calculates all possible scenarios before the move, up to the last move). Such calculations took DeepStack only five seconds.

Such systems can be effective in practical applications, since asymmetric distribution of information is quite common in the real world, for example, when it comes to protecting strategic resources or important medical recommendations.

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

Quantum engine running without heat 11.10.2023

A team of researchers from the Department of Quantum Systems at the Okinawa Institute of Science and Technology (OIST), collaborating with scientists from the University of Kaiserslautern-Landau and the University of Stuttgart, have presented a working quantum engine that operates without the use of heat, unlike traditional mechanisms based on thermodynamic principles.

A quantum engine differs from conventional ones, since its operation is not associated with an explosion of the fuel mixture and air. Instead, scientists change the quantum characteristics of particles in the gas, bypassing the use of heat. At extremely low temperatures, when quantum effects occur, bosons have a lower energy level compared to fermions. This energy gap can be used to power a motor that converts bosons into fermions and vice versa.

Professor Thomas Busch, head of the quantum systems department, explained: "To turn fermions into bosons, we can combine two fermions into a molecule. This new molecule becomes a boson. By destroying it, we can get fermions again. By repeating this cycle, we can create a motor without attracting heat."

Despite the high potential of the new quantum engine, its use in the automotive industry in the near future remains questionable. Keerthi Menon stressed that despite the successful experiments, more research needs to be done to optimize the engine's performance and its possible application in other devices such as batteries and sensors. It is important to maintain low temperatures to preserve the quantum state, which in turn requires significant energy consumption.
