{{further|Computational physics}}
* [[Constraint algorithm]]: a class of algorithms for satisfying constraints for bodies that obey Newton's equations of motion
* [[Demon algorithm]]: a [[Monte Carlo method]] for efficiently sampling members of a [[microcanonical ensemble]] with a given energy
* [[Featherstone's algorithm]]: computes the effects of forces applied to a structure of joints and links
* [[Ground state]] approximation
** [[Variational method]]
*** [[Ritz method]]
* [[N-body problem|''n''-body problems]]
** [[Barnes–Hut simulation]]: Solves the n-body problem in an approximate way that has the order {{math|O(<var>n</var> log <var>n</var>)}} instead of {{math|O(<var>n</var><sup>2</sup>)}} as in a direct-sum simulation.
** [[Fast multipole method]] (FMM): speeds up the calculation of long-ranged forces
* [[Rainflow-counting algorithm]]: Reduces a complex [[stress (physics)|stress]] history to a count of elementary stress-reversals for use in [[fatigue (material)|fatigue]] analysis
* [[Sweep and prune]]: a broad phase algorithm used during [[collision detection]] to limit the number of pairs of solids that need to be checked for collision
* [[VEGAS algorithm]]: a method for reducing error in [[Monte Carlo simulation]]s
* [[Glauber dynamics]]: a method for simulating the Ising Model on a computer
