Perhaps you should try some spelling variations:
"modified invasive convolution algorithms" » "modified invasive evolution algorithm", "modified invasive solution algorithm", "modified invasive ventilation algorithms", "modified passive convolution algorithms"
"modified caging optimizer algorithms" » "modified caging optimized algorithms", "modified caging optimized algorithm", "modified caging optimization algorithms", "modified choosing optimizer 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 invasive convolution algorithms") or ("modified caging optimizer algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified invasive convolution algorithms") OR ("modified caging optimizer algorithms")).
• Removing quotes may allow a broader search: (( modified invasive convolution algorithms ) or ( modified caging optimizer algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified invasive convolution algorithms") or ("modified caging optimizer algorithms"))*.
