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

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 algorithms\") OR (\"modified objective optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( modified total estimation algorithms ) OR ( modified objective optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified total estimation algorithms") OR ("modified objective optimization algorithm"))*.
