What do the neg reference and pos reference mean in  obj reference panel???

 

In card DOBJREF, it says “rk are corresponding reference values, which can take different values depending on whether the response is positive or negative”. Can anyone explain it more clearly? Thanks!

    Thanks Rahul! I have got the meaning of pos/neg referene.

    It means if the value of every member of response is positive (negative),the pos(neg) reference will be used as rk to establish the minmax or maxmin problem.
