Perhaps you should try some spelling variations:
"modified notion approximation algorithms" » "modified network approximation algorithms", "modified time approximation algorithms", "modified one approximation algorithms"
"modified load solution algorithm" » "modified load evolution algorithm", "modified load convolution algorithms", "modified load evolutionary algorithm", "modified adam solution algorithm", "modified near solution algorithm", "modified flour solution algorithm", "modified nodal solution algorithm", "modified global solutions 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 load solution algorithm") OR ("modified notion approximation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified load solution algorithm\") OR (\"modified notion approximation algorithms\"))*".
• Removing quotes may allow a broader search: (( modified load solution algorithm ) OR ( modified notion approximation algorithms ))*.
