Perhaps you should try some spelling variations:
"modified pose estimation algorithms" » "modified pose estimation algorithm", "modified pose optimization algorithms", "modified pose optimisation algorithm", "modified male estimation algorithms", "modified passive estimation algorithms"
"modified invasive evolution algorithm" » "modified invasive solution algorithm", "modified invasive evolutionary algorithm", "modified invasive convolution algorithms", "modified invasive ventilation algorithm", "modified passive evolution algorithm"

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

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