Perhaps you should try some spelling variations:
"modified changing estimation algorithmss" » "modified changing estimation algorithms", "modified changing estimation algorithm", "modified changing optimization algorithms", "modified channel estimation algorithmss", "modified charging station algorithmss", "modified caging estimation algorithmss"
"modified objective predation algorithm" » "modified objective allocation algorithm", "modified objective predators algorithm", "modified objective estimation algorithm"

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 predation algorithm") OR ("modified changing estimation algorithmss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective predation algorithm\") OR (\"modified changing estimation algorithmss\"))".
• Removing quotes may allow a broader search: (( modified objective predation algorithm ) OR ( modified changing estimation algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective predation algorithm") OR ("modified changing estimation algorithmss"))*.
