  We perform numerical experiments on one-dimensional singularly perturbed
problems of reaction-convection-diffusion type, using isogeometric analysis. In
particular, we use a Galerkin formulation with B-splines as basis functions.
The question we address is: how should the knots be chosen in order to get
uniform, exponential convergence in the maximum norm? We provide specific
guidelines on how to achieve precisely this, for three different singularly
perturbed problems.
