This is matlab implementation of the two-phase simplex method for better understanding of the algorithm.

• Smallest Index Rule (SIR): Blend's rule

• Largest Index Rule (LIR): Reverse of SIR

• Successive Ratio Rule (SRR): Lexicographic order

$ matlab -r main 

• You can change the file to import (in main.m)

t = importdata('./data/XXX.txt', ' '); 

• You can choose mode 'SIR' by (in main.m)

mode = 'SIR'; 

• Data Format Example (stadard form)

-5 -6 -1 -4 -5 0 0 0 20 2 1 1 1 1 0 0 10 1 0 2 1 0 1 0 5 1 1 1 0 0 0 1
