Perhaps you should try some spelling variations:
"modified total estimation algorithms" » "modified total estimation algorithm", "modified total optimization algorithms", "modified total optimisation algorithm", "modified motion estimation algorithms", "modified pose estimation algorithms", "modified total variation algorithms", "modified thermal estimation algorithms", "modified ti6al4v estimation algorithms"
"modified objective solution algorithm" » "modified objective evolutionary algorithm", "modified objective allocation algorithm", "modified objective evolution algorithm", "modified objective convolution algorithms"

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 solution algorithm") OR ("modified total estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective solution algorithm\") OR (\"modified total estimation algorithms\"))".
• Removing quotes may allow a broader search: (( modified objective solution algorithm ) OR ( modified total estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective solution algorithm") OR ("modified total estimation algorithms"))*.
