Title
The local integro splines with optimized knots
Abstract
This paper presents a new approach to optimize knots of local integro splines that approximate given function integrals. The problem of computing knots is reformulated as $$L_1$$ convex optimization problem, in which both the number of knots and their locations can be automatically determined at the same time. The numerical examples show that approximation integro splines obtained by our method have few knots, while satisfying the fitting precision.
