  2. Atmospheric dispersion modeling - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_dispersion...

    A great many computer programs for calculating the dispersion of air pollutant emissions were developed during that period of time and they were called "air dispersion models". The basis for most of those models was the Complete Equation For Gaussian Dispersion Modeling Of Continuous, Buoyant Air Pollution Plumes shown below: [4] [5]

  3. Game theory - Wikipedia

    en.wikipedia.org/wiki/Game_theory

    Separately, game theory has played a role in online algorithms; in particular, the k-server problem, which has in the past been referred to as games with moving costs and request-answer games. [125] Yao's principle is a game-theoretic technique for proving lower bounds on the computational complexity of randomized algorithms , especially online ...

  4. Graphical game theory - Wikipedia

    en.wikipedia.org/wiki/Graphical_game_theory

    The graphical form is an alternate compact representation of a game using the interaction among participants. Consider a game with players with strategies each. We will represent the players as nodes in a graph in which each player has a utility function that depends only on him and his neighbors. As the utility function depends on fewer other ...

  5. List of games in game theory - Wikipedia

    en.wikipedia.org/wiki/List_of_games_in_game_theory

    Sequential game: A game is sequential if one player performs their actions after another player; otherwise, the game is a simultaneous move game. Perfect information : A game has perfect information if it is a sequential game and every player knows the strategies chosen by the players who preceded them.

  6. Three utilities problem - Wikipedia

    en.wikipedia.org/wiki/Three_utilities_problem

    , is a graph with six vertices and nine edges, often referred to as the utility graph in reference to the problem. [1] It has also been called the Thomsen graph after 19th-century chemist Julius Thomsen. It is a well-covered graph, the smallest triangle-free cubic graph, and the smallest non-planar minimally rigid graph.

  7. Air pollution - Wikipedia

    Air pollution deaths by nation due to fossil fuels. India and China have the higher number of deaths from air pollution. In India, it contributed to 2.1 million deaths in 2021, whereas China saw 2.4 million deaths. [128] In some countries, more than 20% of deaths were attributed to air pollution, for instance in Nepal, Bangladesh, Laos and ...

  8. Move by nature - Wikipedia

    en.wikipedia.org/wiki/Move_by_nature

    In game theory a move by nature is a decision or move in an extensive form game made by a player who has no strategic interests in the outcome. The effect is to add a player, "Nature", whose practical role is to act as a random number generator .

  9. Ringelmann scale - Wikipedia

    en.wikipedia.org/wiki/Ringelmann_scale

    Ringelmann smoke charts, 1897. The Ringelmann scale is a scale for measuring the apparent density or opacity of smoke. [1] [2] It was developed by a French professor of agricultural engineering Maximilien Ringelmann of La Station d'Essais de Machines in Paris, who first specified the scale in 1888.
