Perhaps you should try some spelling variations:
"modified write optimisation algorithmsss" » "modified write optimization algorithms", "modified write estimation algorithms", "modified write optimization algorithmssss", "modified write estimation algorithmsss", "modified write estimation algorithmssss"
"modified objective optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective estimation algorithm", "modified objective estimation algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified objective optimisation algorithm") OR ("modified write optimisation algorithmsss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective optimisation algorithm\") OR (\"modified write optimisation algorithmsss\"))".
• Removing quotes may allow a broader search: (( modified objective optimisation algorithm ) OR ( modified write optimisation algorithmsss )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimisation algorithm") OR ("modified write optimisation algorithmsss"))*.
