hello

I'm searching for an optimized patch for inequation system resolution like this one:

{ minDyn < |x1| + |x2| + |x3| + |x4| < maxDyn; minMove < |x1| < maxMove; minMove < |x2| < maxMove; minMove < |x3| < maxMove; minMove < |x4| < maxMove; minStep < x1 + x2 + x3 + x4 < maxStep; }

minDyn,maxDyn,minMove,maxMove,minStep and maxStep are integers chosen by the user x1,x2,x3 and x4 are integers

any help will be highly appreciated!

Thank you

Pierre
