Working on an optimization problem formulated as an MIP where I have two decision variables a[i,j] and b[u,v,x,y]. I have a couple of equations (EQ1,.., EQ10). For simplicity and abstraction levels I just mention EQ1 and EQ2.
For a special case I need to express this situation :
If x!=y and a[u,x] = 1 and a[v,y] =1 then
consider linear equation EQ1 // EQ1 for the special case
otherwise consider EQ2.
Does any one know how to deal with this situation ? Any help will be highly appreciated.
