Perhaps you should try some spelling variations:
"modified objective optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective estimation algorithm"
"modified write estimation algorithms" » "modified write estimation algorithm", "modified write optimization algorithms", "modified write approximation algorithms", "modified risk estimation algorithms", "modified pose 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 objective optimisation algorithm\") OR (\"modified write estimation algorithms\"))~".
• Removing quotes may allow a broader search: (( modified objective optimisation algorithm ) OR ( modified write estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimisation algorithm") OR ("modified write estimation algorithms"))*.
