WebAbstract: Practical use of SJF scheduling algorithm (SPN or Shortest Process Next), which is one of the best scheduling algorithms, always has some difficulties because when an operating system wants to execute a process, it does not know the execution time of it. After running, the exact execution time of that process would appear.
