Opus Magnums 和zach以往的游戏相比最明显的特点是，几乎每关都有一个非常明显可达到的理论最优解。这使我们的优化过程变得比较愉快。以这个教学关为例来看看是如何抵达最优解的。
Compared with previous games of zachtroincs, Opus Magnum always has a theoretical optimal solution for each three index--CHEAP, NEAT, QUICK, which make the optimization become a 'joyful' process. Here, use the tutorial level as an example.

基本上所有的谜题都能用一个操作臂解决，普通操作臂不行就上活塞臂，还不行就上轨道。所以最便宜的解就是只用一个臂的解（如果一定要用到活塞臂或者轨道，可能需要多斟酌一下）。
Basicly, every puzzle can be solved by only one arms, if it's not, use a piston, if it still doesn't work, then consider to add few tracks. So the find the cheapest solution is just to find out how to solve by only one arm (if it need tracks, you may need a second think).

下面没有垫东西的时候不要旋转枢轴，多用活塞，尽量紧凑排列，不要空挥机械臂。
Try not use pivots when the below are empty cells, use more pistons, arrange the components as compact as possible, try not rotate the arms over empty cells

弄清楚一件事，从INPUT里面取出元素的最大速率是每2TICK一个，需要2个机械臂，把所有的过程全部拆分，一个机械臂只做一件事：抓取，做事，复位。这样一来所有机械臂全部是4TICK的周期，大多数情况下可以得到最速解。
Just need to know one thing, the max speed to can pull elements from an input is 1 per 2 ticks. So you need to resolve the process, let a arm do only one thing: grab, do somthing, reset. Then all the arms has a 4 ticks loop, in most condition you can get the quickest solution.
