Questions tagged [computation]

Computation is paramount to the discipline of computer science, and deals with the type and use of computing technology in information processing, in particular, in the context of an algorithm, or a protocol.

From Wiki

In the theory of computation, a diversity of mathematical models of computers have been developed. Typical mathematical models of computers are the following:

  • State models including Turing machine, push-down automaton, finite state automaton, and PRAM
  • Functional models including lambda calculus
  • Logical models including logic programming
  • Concurrent models including actor model and process calculi

Calculate XP percentage completed for multiple levels (similar to call of duty/etc)

I am developing an XP/Leveling system for a website. Think of it like Call of Duty levels. For example Level 1 = 0 - 100XP Level 2 = 100 - 200XP Level 3 = 200 - 300XP Now obviously for level 1, since it's 100 level max, I can do const currentXp =…
