Perhaps you should try some spelling variations:
componente convex » componente conexa (Expand search), componente chave (Expand search), componente confiavel (Expand search)
mono componente » sono componentes (Expand search), solo componente (Expand search), novo componente (Expand search)
convex program » convex programs (Expand search), conviver program (Expand search), softex program (Expand search)
costing method » cost method (Expand search)
using costing » using coating (Expand search), using boosting (Expand search), using coatings (Expand search)
method python » method method (Expand search), python python (Expand search)
coder mono » under mono (Expand search)

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: "(( coder mono componente convex program ) OR ( using costing method python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( coder mono componente convex program ) OR ( using costing method python programming ))*.
