Mapping the right algorithm to a real world need is lot more difficult as real world needs always have differences with the problems that the published algorithms solve. This is my experience. So, I end up most of the time devise my own method to solve things. When you are hard pressed for time, it is often difficult to run through books and find the right ones. The mind to read and understand complex algorithms is often overtaken by the mind to just go and solve the problem in hand in your own way.
