Perhaps you should try some spelling variations:
"modified objective solution algorithm" » "modified objective evolutionary algorithm", "modified objective allocation algorithm", "modified objective evolution algorithm", "modified objective convolution algorithms"
"modified near approximation algorithms" » "modified one approximation algorithms", "modified network approximation algorithms", "modified _ approximation algorithms", "modified seird approximation algorithms", "modified adam approximation algorithms"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective solution algorithm") OR ("modified near approximation algorithms"))~.
• Removing quotes may allow a broader search: (( modified objective solution algorithm ) or ( modified near approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective solution algorithm") or ("modified near approximation algorithms"))*.
