Hi all! I have four equations (eq1=0, ..., eq4=0) with the the four unknowns (y1, y2, y3, y4) in exponentials. I know the interval where the solutions are, and I solve this equation set by means of FindRoot by obtaining set of solutions. Then, I make a selection between the obtained results. However, I have a dependency between variables: y1<y2<y3<y4 mR = Table[FindRoot[{eqn1 == 0, eqn2 == 0, eqn3 == 0, eqn4 == 0}, {y1, Random[Real, {a, b}]}, {y2, Random[Real, {a, b}]}, {y3, Random[Real, {a, b}]}, {y4, Random[Real, {a, b}]}], {24}]; My question is Is there any way of include the relation between y1, ..., y4 in the selection of them by Random. Something like {y2, Random[Real, {y1, b}]}, {y3, Random[Real, {y2, b}]}, ... I hope I have clearly explained my problem. Thanks
