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