As we know that Anaplan works on Linear Programming principle, it gets challenging to solve Non-linear problems. One such problem is minimizing absolute difference of 2 variables. Following is the solution for the same -
Equation |a-b|<= c
where - a, b are decision variables, c is decision variable
Below constraints need to be applied and c is a positive variable a - b <= c b - a <= c
Finally you achieve "c" value from optimizer which is the absolute difference.
