Using the Trees (Or/And) for Enumerating Expression of Context-Free Languages // Tomsk State Pedagogical University Bulletin. 2004. Issue 6 (43). P. 84-88

Issues of AND-OR trees, used to build enumeration algorithms and objects generation, are considered within the article. Properties and algorithms of AND-OR trees listed are described in detail. Analysis is conducted to view the possibilities to apply AND-OR trees for context-restricted grammar(s). A method is offered to refer to build the algorithms of context-restricted grammar(s) enumeration. An example is examined to build enumeration algorithm as applied to arithmetic expressions

The conceptual models of the com¬puter scholastic programs. // Tomsk State Pedagogical University Bulletin. 2005. Issue 7 (51). P. 138-143

Three conceptual models of the computer scholastic programs are considered. The first is founded on use the information approach and is oriented on building of the CBI programs. Rests are founded on idea of the artificial intelligence. It Is Described main variants and generalized structures of the models. It is shown that forerunner in realization more simply; however, realiza¬tion of the knowledge-based computer scholastic pro¬grams provides the more qualitative process of the edu¬cation.
