A statement in a formal system that has proof . Theorization is the process of building mathematical models for how things work.
Scientists always desire theories that are simpler than the data they explain.
See also Occam's Razor and simulation . The problem of determining the future positions and velocities of three gravitational bodies. The problem was proved unsolvable in the general case by Henri Poincar , which forshadowed the importance of chaos . Although no analytical solutions are possible in the worst case, a numerical solution is sometimes sufficient for many tasks. Time Complexity A function that describes the amount of time required for a program to run on a computer to perform a particular task.
