*86*, but what about GCR? After all, GMRES is an incremental modification of GCR. It also contains mispredictions like: "In practical implementation it is usually more suitable to replace the Gram-Schmidt algorithm of step 2 by the modified Gram-Schmidt algorithm" If someone uses LGMRES, would we produce a citation only to Baker et al, or also to Saad & Schultz? What about the BiCG family, containing many more variants that are slight variations on existing methods? Or identical methods that were published twice under different names?
