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 algorithm"
"modified allocation estimation algorithmss" » "modified allocation estimation algorithms", "modified allocation estimation algorithm", "modified allocation optimization algorithms", "modified allocation optimization algorithmss", "modified motion estimation algorithmss"

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 optimization algorithm") OR ("modified allocation estimation algorithmss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective optimization algorithm\") OR (\"modified allocation estimation algorithmss\"))*".
• Removing quotes may allow a broader search: (( modified objective optimization algorithm ) OR ( modified allocation estimation algorithmss ))*.
