Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithms
changing estimation » channel estimation, charging station
static optimization » stage optimization, stochastic optimization, staffing optimization
modified changing » modified caging

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified changing estimation algorithm ) OR ( modified static optimization algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified changing estimation algorithm ) OR ( modified static optimization algorithm ))*.
