// For example if elimination_groups is a vector of size k, then
// the linear solver is informed that it should eliminate the
// parameter blocks 0 ... elimination_groups[0] - 1 first, and
- // then elimination_groups[0] ... elimination_groups[1] and so
+ // then elimination_groups[0] ... elimination_groups[1] - 1 and so
// on. Within each elimination group, the linear solver is free to
// choose how the parameter blocks are ordered. Different linear
// solvers have differing requirements on elimination_groups.
