Perhaps you should try some spelling variations:
"modified nodal convolution algorithms" » "modified nodal evolution algorithm", "modified nodal solution algorithm", "modified nodal solution algorithms", "modified adam convolution algorithms", "modified near convolution algorithms"
"modified allocation estimation algorithms" » "modified allocation optimization algorithms", "modified motion estimation algorithms", "modified allocation estimation algorithm", "modified allocation optimisation algorithm"

Try widening your search to All Fields.

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

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