  Adaptive, locally refined and locally adjusted meshes are preferred over
uniform meshes for capturing singular or localised solutions. Roughly speaking,
for a given degree of freedom a solution associated with adaptive, locally
refined and locally adjusted meshes is more accurate than the solution given by
uniform meshes. In this work, we answer the question which meshes are better
conditioned. We found, for approximately same degree of freedom (same size of
matrix), it is easier to solve a system of equations associated with an
adaptive mesh.
