2. Hungarian algorithm - Wikipedia

   en.wikipedia.org/wiki/Hungarian_algorithm

   The Hungarian method is a combinatorial optimization algorithm that solves the assignment problem in polynomial time and which anticipated later primal–dual methods.It was developed and published in 1955 by Harold Kuhn, who gave it the name "Hungarian method" because the algorithm was largely based on the earlier works of two Hungarian mathematicians, Dénes Kőnig and Jenő Egerváry.

3. Stiff equation - Wikipedia

   en.wikipedia.org/wiki/Stiff_equation

   Stiff equation. In mathematics, a stiff equation is a differential equation for which certain numerical methods for solving the equation are numerically unstable, unless the step size is taken to be extremely small. It has proven difficult to formulate a precise definition of stiffness, but the main idea is that the equation includes some terms ...

   Also, such software supports metacognition by making all steps in a problem or a construction visible and editable, so children can reflect on individual steps or the whole journey. Social media. Online communities and forums allow educators, researchers and students to share, discuss and remix elementary mathematical content they find or create.

6. Equation solving - Wikipedia

   en.wikipedia.org/wiki/Equation_solving

   Solving an equation symbolically means that expressions can be used for representing the solutions. For example, the equation x + y = 2x – 1 is solved for the unknown x by the expression x = y + 1, because substituting y + 1 for x in the equation results in (y + 1) + y = 2 (y + 1) – 1, a true statement. It is also possible to take the ...

7. Mathematical problem - Wikipedia

   en.wikipedia.org/wiki/Mathematical_problem

   A mathematical problem is a problem that can be represented, analyzed, and possibly solved, with the methods of mathematics. This can be a real-world problem, such as computing the orbits of the planets in the solar system, or a problem of a more abstract nature, such as Hilbert's problems. It can also be a problem referring to the nature of ...
