Simplex solver and tableau printer written in C++. Input a tableau and perform any operations you want.
Input file format is as in input.txt, variables should be written along the first row.
Run the program with
tableau-printer input.txt
Also note that with Tableau<Fraction<int>>, most real problems won't be solvable, since the ints in Fraction will overflow. However, for pretty-printing nice example tableaus, this works nicely. For the latter, consider Tableau<Double> but be wary of rounding errors..
Some of the features listed in the menu aren't yet implemented. Implementations and suggestions for more features are welcome.
I've moved the LaTeX making code into a bash script latexify.sh. Simply save the output of the program into a file and then run
cat output.txt | ./latexify.sh to get LaTeX output. Make sure to\usepackage{amsmath}. If you want to have mathematical symbols in the LaTeX output, simply name the variable \zeta, x_1 or whatever tickles your fancy.
