Scientific Computing Dept. [Part 1]

well..

i just wanted to write some about the department i've choosen to continue with in my final year at FCIS as you can feel from the title of the topic "Part 1" which means the first term of the year basically it was not as i expected "actually i dont know what was i expecting :D "

but it was better i think it's the only department that you are given the problem and some basic knowladge and you have to make implement an algorithm and that's exactly the ACMer's life :)

i'll give a short note on every subject from the first term

First : Scientific Visualization

Troubleshooting in ACM-ICPC Contest

i've participated in many contests as organizer, specifically in the technical stuff which is mainly two portions

  • The IDE which is mainly "eclipse"
  • The contest communication tool which can't be except "pc2"

and in the last contest i've participated in it's technical preparations i faced a number of troubles

lets take them one by one

1.Teams don't connect to the Server which is a Linux Machine

  • Solution : before you open the server edit the "pc2server" file and edit this line
  • java -Djava.security.policy=policy.ini $PC2CN $*
  • to be
  • java -Djava.rmi.server.hostname="10.106.0.35" -Djava.security.policy=policy.ini $PC2CN $*
  • of course change the ip according to your server ip

and make this edit in all the executables you will run {team, board, judge.....}

bye bye MS !! i said those words one day that i started to install Linux i had a fear that i go back to windows a day or more after i install it, but now i dont think that i'm going back to windows :D i can feel that my computer feels democracy :D every time i look on the requirments for a software , game or windows i look on the minimum requirments section to see if my PC will handle it or not as i know that the recommended requirments will be not in my PC :D with linux i saw the minimum , recommended and searched for any other requirments to see this is the recomended requirments published on Ubuntu official website

  • Sound card

  • A network or Internet connection

lol, i feel that i can run this OS on a gameboy and it will run smoothly

Visual Algorithms [Graph Algorithms]

here is one of the assignments i liked to be doing in Scientific Computing

specifically a Mathematical Programming assignment i could have just implemented a Console application running the algorithm and get my marks, but thats not what i need from SC Dept :)

i think it would be useful for those who want to learn one of the algorithms it runs or for those who want to see what a SC assignment looks like :P well here is the main form  Visual Algorithms Main Form
