Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithms"
"modified pose estimation algorithm" » "modified male estimation algorithm", "modified passive estimation algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified pose estimation algorithm") or ("modified multiobjective optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified pose estimation algorithm") OR ("modified multiobjective optimization algorithm")).
• Removing quotes may allow a broader search: (( modified pose estimation algorithm ) or ( modified multiobjective optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified pose estimation algorithm") or ("modified multiobjective optimization algorithm"))*.
