Perhaps you should try some spelling variations:
"modified allocation optimization algorithms" » "modified allocation optimisation algorithm", "modified allocation estimation algorithms", "modified allocation estimation algorithm", "modified location optimization algorithms"
"modified through convolution algorithms" » "modified through evolution algorithm", "modified through solution algorithm", "modified through evolution algorithms"

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