To model |x| in an LP, you typically create two new variables, x^- and x^+. Constrain them both to be nonnegative: x^-, x^+ >= 0 Then each time you have x in your model, replace it with x^+ - x^-, and each time you have |x|, replace it with x^+...

BLAS was designed to provide low-level routines necessary to implement common linear-algebra operations (it is the "Basic Linear Algebra Subprograms", after all). To name just one of many uses, getting the largest-magnitude element of a vector is necessary for pivot selection in LU factorization, which is one of the most...

You can use the conditional operator and the unary negation operator: function absVal(integer) { return integer < 0 ? -integer : integer; } ...

The shifts are not useless. It is a form of banchless logic that Hexray did not manage to reproduce in its c disassembly. .text:0040DD55 movsx eax, si .text:0040DD58 cdq .text:0040DD59 xor eax, edx .text:0040DD5B sub eax, edx .text:0040DD5D and eax, 7 .text:0040DD60 xor eax, edx .text:0040DD62 sub eax, edx Is...

bool fun(int i,int j) { return abs(i)<abs(j); } sort() need some function has return bool type and it accept your int function because it can assume if it return 0 it is false else it is true. You shoudl just give it it is true or not then let sort()...

Embarrassingly the problem was the "100 -" which should have been "1 -" as the values being compared are stored as decimals formatted as percentages. Thank you for the responses, I'll make sure to observe the 'minimal' aspect of the best practice doc that pnuts shared in future, same point...
