We give an Ok · n2) algorithm for the 1-Sided Crossing Minimization problem, thus showing that the problem is Fixed Parameter Tractable. The constant ø in the running time is the golden ratio \( \phi = \frac{{1 + \sqrt 5 }} {2} \approx 1.618 \) . The constant k is the parameter of the problem: the number of alloweded ge crossings.
