Perhaps you should try some spelling variations:
"modified invasive evolution algorithm" » "modified invasive solution algorithm", "modified invasive evolutionary algorithm", "modified invasive convolution algorithms", "modified invasive ventilation algorithm", "modified passive evolution algorithm"
"modified orca predation algorithm" » "modified orca predators algorithm", "modified orca estimation algorithm", "modified dorca predation algorithm", "modified orcad predation algorithm", "modified ohca predation 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 invasive evolution algorithm") or ("modified orca predation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified invasive evolution algorithm") OR ("modified orca predation algorithm")).
• Removing quotes may allow a broader search: (( modified invasive evolution algorithm ) or ( modified orca predation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified invasive evolution algorithm") or ("modified orca predation algorithm"))*.
