Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
near optimisation » _ optimisation, network optimization
force algorithm » source algorithm, search algorithm
modified near » modified seird, modified adam
using force » using morse, cutting force
code » core

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: (( code using force algorithm ) OR ( modified near optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( code using force algorithm ) or ( modified near optimisation algorithm ))*.
