TABLE 7.6.

Comparison of nBIE and dBIE formulations on 20 example proteins. Error is computed with respect to the numerical solutions on the same mesh using a much lower GMRES tolerance (10⁻⁷).

geometry formulation	A-Spline nBIE	A-Spline dBIE	Linear dBIE
median # iterations	40	17	^*
max # iterations	47	26	^*

median energy error	11.28	0.12	50.65
max energy error	17.55	0.46	61.92

Computation was halted after 100 GMRES iterations: each computation involving linear geometry reached 100 iterations.
