    Hello Andres,

    Here's my pdf of the solution. I added an explanation of how to compute the circles. The method works nicely in these problems from Antoine, since he intentionally doesn't tell us a good estimated position to start with - the circle method needs no AP at all. The circles reduce the number of iterations needed - but of course the computer has to do quite many iterations in finding a fix with the circles (I'm using non-linear least squares estimation from the "Scipy" library).

    Your cover is wonderful!

    Best,
    Harri
