In addition to temporal views, frames can be related to different space views. A great part of possible relations are represented by these natural means. Of course, conventional mathematical functions are also used. However, their role is drastically decreased. The film notation improves the mental simulation of application algorithms and gives greater assurance that the design of a method is correct.
Film can provide more information than text, graphic, and image.
They were developed many-many years ago by ancient people. Technologies were very poor in the past. These signs are flexible and multi-media signs. Though there are literally thousands of algorithms, there are very few design techniques. A great variety of the best and most widely used computer algorithms are reduced to this model.
