Isogeometric analysis: An overview and computer implementation aspects (2012, methodology): “Recently a collocation scheme based on superconvergence theory was proposed in [2], which has been observed to give more accurate results at the expense of more basis function evaluations.”
The variational collocation method (2016, methodology): “Although the existence and the location of these points have not been widely studied for splines of maximum continuity, it is known that such points exist [47] and they have been recently used for an overdetermined (least-square) collocation scheme [48].”
Reduced integration at superconvergent points in isogeometric analysis (2018, methodology): “Therefore a least-squares collocation method was proposed in [22] to solve the overdetermined system of equations obtained by writing the collocated strong form at all points.”
An isogeometric collocation method for frictionless contact of Cosserat rods (2017, background): “The optimal choice of the collocation points is an aspect on which very recent advances have been reported [17, 18].”
