1950s

• Hestenes, Stiefel, and Lanczos, all from the Institute for Numerical Analysis at the National Bureau of Standards, initiate the development of Krylov subspace iteration methods.^{[9][10][11][12]} Voted one of the top 10 algorithms of the 20th century.
• Equations of State Calculations by Fast Computing Machines introduces the Metropolis–Hastings algorithm.^[13] Also, important earlier independent work by Alder and S. Frankel.^[14][15]

1960s

• First recorded use of the term "finite element method" by Ray Clough,^[21] to describe the methods of Courant, Hrenikoff and Zienkiewicz, among others. See also here.
• Using computational investigations of the 3 body problem, Minovitch formulates the gravity assist method.^[22][23]
• Molecular dynamics was invented independently by Aneesur Rahman.^[24]
• Kruskal and Zabusky follow up the Fermi–Pasta–Ulam problem with further numerical experiments, and coin the term "soliton".^[25][26]
• Edward Lorenz discovers the butterfly effect on a computer, attracting interest in chaos theory.^[27]
• Frenchman Verlet (re)discovers a numerical integration algorithm,^[28] (first used in 1791 by Delambre, by Cowell and Crommelin in 1909, and by Carl Fredrik Störmer in 1907,^[29] hence the alternative names Störmer's method or the Verlet-Störmer method) for dynamics, and the Verlet list.^[28]

1970s

• Mandelbrot, from studies of the Fatou, Julia and Mandelbrot sets, coined and popularized the term 'fractal' to describe these structures' self-similarity.^[30][31]

1980s

• Fast multipole method invented by Rokhlin and Greengard (voted one of the top 10 algorithms of the 20th century).^[35][36][37]

1990s

• The appearance of the first research grids using volunteer computing – GIMPS (1996), distributed.net (1997) and Seti@Home (1999).
• Kepler conjecture is almost all but certainly proved algorithmically by Thomas Hales in 1998.

2000s

• In computational group theory, God's number is shown to be 20.^[38][39]
