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