Perhaps you should try some spelling variations:
mathematical » mathematics (Expand Search), matematico (Expand Search)
matematicas » tematicas (Expand Search)
matematica » tematica (Expand Search)
algorithms." » algoritmo." (Expand Search), algoritmos." (Expand Search)
algoritmos." » algoritmo." (Expand Search)
algorithm." » algoritmo." (Expand Search)

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: "((mathematical OR matematicas) OR matematica) ((algorithms." OR algoritmos.") OR algorithm.")~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((mathematical OR matematicas) OR matematica) ((algorithms.\" OR algoritmos.\") OR algorithm.\")".
• Removing quotes may allow a broader search: ((mathematical OR matematicas) OR matematica) ((algorithms. OR algoritmos. ) OR algorithm. ).
• Adding a wildcard symbol may retrieve word variants: "((mathematical OR matematicas) OR matematica) ((algorithms." OR algoritmos.") OR algorithm.")*.
