Ward, Rabab K. On on-line adaptation for discrete \(\ell_ 1\) linear estimation. (English) Zbl 0532.65008 IEEE Trans. Autom. Control 29, 67-71 (1984). A recursive algorithm for the \(\ell_ 1\) estimation problem is presented. The case of updating the optimal estimates when an extra point is to be added or when an old point is to be deleted are discussed separately. A numbered example is given.
