One possible pitfall of such a self-adaptive property is the occurrence of attracting regions: if the Lévy flights (({L^{i}_{t}})_{t in mathbb {N}}(i=1,2)) enter regions of high quality and get the response from the quality evaluation step to focus their search (by decreasing their diffusivity), an improper quality rating mechanism might cause the Lévy flights to stay there forever.
The Department of Health and Human Services has estimated a national improper payment rate for Medicaid of 9.4 percent (with the federal share estimated at $22.5 billion) for fiscal year 2010.
