Perhaps you should try some spelling variations:
"modified one approximation algorithms" » "modified time approximation algorithms", "modified _ approximation algorithms", "modified rough approximations algorithms", "modified male approximation algorithms", "modified near approximation algorithms", "modified orca approximation algorithms"
"code using mental algorithm" » "code using genetic algorithm", "code using control algorithm", "code using mppt algorithm", "code using metal algorithm", "code nursing mental algorithm", "code using medical algorithm", "core using mental algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("code using mental algorithm") or ("modified one approximation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("code using mental algorithm") OR ("modified one approximation algorithms")).
• Removing quotes may allow a broader search: (( code using mental algorithm ) or ( modified one approximation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("code using mental algorithm") or ("modified one approximation algorithms"))*.
