LPT-Johnson-rule

This is a course project. It is created by Xinman Liu.

C language is used to implment longest processing time(LPT) rule and Johnson's rule.

• To compile the program, use command line:

  gcc -Wall -std=c99 -o a3 a3.c
  

• To generate 400 000 instances txt files, use command line:

  ./a3 -r
  

• To test whether ratio is calculated correctly or not, use command line:

  ./a3 -i <instancem_n_t1_t2_i.txt
  

  (or any other valid txt file name; and please delete all comment lines in the instances!)

  (it will print out ratio for this instance to stdout)

• To get result.txt, first, make a new directory "ratio" on the Desktop. Then, run shell script using this command line:

    sh run.sh
  

  or you can use:

    chmod 700 run.sh
    
    ./run.sh
