Horrible's Tips

• Do small cases! Let the pencil (or the computer) do the work and use your brain to look out for patterns.

• Try to find the most natural and simple way of modeling the problem.

• Learn how to code a decision tree, or other models to exhaustively search for constructions, proof patterns, recursive complete search, etc. and build intuition on that to solve the more general cases of the problem.

• 做小案例！让铅笔（或电脑）完成工作，用你的大脑寻找规律。
• 尝试找到最自然、最简单的问题建模方法。
• 学习如何编码决策树，图或其他模型，以详尽考虑构造、证明模式、递归完全遍历等，并在此基础上建立直觉，以解决更一般的问题。
