Solving a problem, even a completely new problem, can be approached systematically to some extent. For a problem requiring iterative passes of decomposition, a and approach can be adopted, in which multiple stages of decomposition take place. If a problem can be broken into , it can be easier to solve. Even then, there are still additional techniques that might be needed. is the means by which we focus at the necessary level of detail, disregarding other levels. A(n) is an abstraction of how binary digits are stored on a disk. Using is another.
Complex problems can have multiple solutions, some better than others, and is a means of reverting to a previous state in order to look for a more optimal solution. An example of this would be . For more complex problems, a(n) might be used, which is a head start for an algorithm to solve a problem more quickly. An example of this would be a satnav disregarding routes .
