Perhaps you should try some spelling variations:
construction algorithms » convolution algorithms
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
passive construction » adaptive construction, discursive construction
near optimization » network optimization, stage optimization, _ optimization
modified passive » modified adaptive
modified near » modified seird, modified adam

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 passive construction algorithms ) OR ( modified near optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified passive construction algorithms ) or ( modified near optimization algorithm ))*.
