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