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 caging estimation algorithmss" » "modified caging estimation algorithms", "modified caging estimation algorithm", "modified caging optimization algorithms", "modified lighting estimation algorithmss"

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