first, beta=-(V\W); alpha=W*(V+W*beta); is just 1 way to find a suitable solution alpha == w (v + w beta). I’m needing to find other ways in order to get different results. Let’s give a numerical example : V=25 c=60 W=3 b=85 f=-1 give : alpha=3 beta=-8 nfr=[-4, -1/9]~ of course with such small values, there’s no possible different end result than [-4, -1/9], but the real numbers are around 300 digits long.
