[펌]Code tunning을 위한 규칙 - programming pearls

1. data structure augmentation
    부가적인 정보를 활용한다.

2. store precomputed results

3. caching

4. lazy evaluation - 불필요한 evaluation을 피함

5. packing - 압축

6. interpreters

7. code motion out of loops
   - loop 내부의 내용을 최소화 한다.

8. combining tests
   - 경계 test대신 sentinel을 둔다.

9. loop unrolling
  - loop를 풀어쓴다.

10. transfer-driven loop unrolling

11. unconditional branch removal

12. loop fusion

13. exploit algebraic identitied

14. short-circuiting monotone functions

15. reordering testss

16. precompute logical functions

17. boolean variable elimination

18. collapsing function hierarchies

19. exploit common cases

20. coroutines

21. transformations on recursive functino

22. parallelism

23. compile-time initialization

24. exploit algebraic identities
     monotonicity이용, incremental algorithms 이용

25. common subexpression elimination

26. paring computation

27. exploit word parallelism
