Online Problem solver

The online solver is a platform that comprises of a set of webservices that solve well known problems in computer science that I use frequently.

For the time being the following solvers are available:

  1. Basic Network tutorial
  2. Disk scheduling solver
  3. Information retrieval – basic calculator (from SYSPRO 2018)
  4. Process scheduling solver
  5. Page replacement algorithm solver

Also, available are the following services:

  1. The makefile generator

Various are algorithms are planned.

In the future more will be added but there is no specific date plan since I am developing them in my spare time.

Online Disk Scheduling Solver

The Online Disk scheduling solver supports the following algorithms: FCFS, SSTF, SCAN, LOOK, C-SCAN and C-LOOK for up to 10 disks.

Please note the following:

  1. The solver is provided to you for free. It is an unofficial and unsupported tool.
  2. The solver has not been extensively tested. It should generate correct results for simple examples.
  3. It is based on the examples provided by Professor Stathes Hadjiefthymiades (University Of Athens) at his class and on the examples provided in various books related to the topic of Operating Systems.
  4. It is a tool that you can use in order to understand how disk scheduling works.

You should always verify the solution generated by hand.

If you a find a bug you can report it via the contact form. If I have spare time I will fix it.
