vertices of the windmill.
A ''' complex windmill''' is the graph obtained by coalescing a
complete graph <math>K_{r}, \; r \geq 2</math>, with disjoint graphs <math>S_{1},
S_{2}, \ldots, S_{p}</math> at <math>p</math> distinct vertices of <math>K_{r}, \; 0 \leq p
\leq r</math>, so that these vertices are cut vertices of the complex
windmill.
