Perhaps you should try some spelling variations:
"modified objective optimization algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective estimation algorithms"
"modified total estimation algorithm" » "modified motion estimation algorithm", "modified pose estimation algorithm", "modified total variation algorithm", "modified thermal estimation algorithm", "modified ti6al4v estimation algorithm"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified total estimation algorithm\") OR (\"modified objective optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( modified total estimation algorithm ) OR ( modified objective optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified total estimation algorithm") OR ("modified objective optimization algorithm"))*.
