The   following  problems lead an ”overflow error” during the iteration FOR ALL THE ALGORITHMS

  Diagonal 1,  Diagonal 3, Hager,   BDQRTIC (CUTE)  EG 2(CUTE),   STAIRCASE S1,  DIXON3DQ (CUTE)  and  DIXMAANL (CUTE).


It should be note that We use ”F” to denote that the corresponding algorithm does not achieve the given iteration tolerance

||g_{k}|| ≤ 10^{-5} or overflow appears for

the algorithm.  Meanwhile, we also stop if the iteration number exceeds 2000 .
