| Abstract | The class of self-P-printable sets, those sets that are enumerable in polynomial time relative to themselves, has been shown to be the same as the class of sets that have small generalized Kolmogorov complexity relative to themselves [J. Hartmanis and L. Hemachandra, Proc. 3rd Annual Symposium on Theoretical Aspects of Computer Science, Springer-Verlag, Berlin, New York, 1986, pp. 321333] and [J. Balczar and R. Book, Acta Informatics, 23 (1986), pp. 679688]. This class properly includes the sets of small generalized Kolmogorov complexity, including the tally sets. The class of sets polynomial time Turing equivalent to a tally set includes the class of self-P-printable sets [J. Balczar and R. Book, op. cit.], and the inclusion is clearly proper because every self-P-printable set must be sparse while there are many nonsparse sets (such as all nonsparse sets in P) that are polynomial time Turing equivalent to a tally set.The question of whether or not the class of self-P-printable sets is the same as the class of sparse sets that are polynomial time Turing equivalent to a tally set is addressed here. Necessary and sufficient conditions for the equivalence of these two classes are presented. Also presented are relativizations for all possible combinations of these necessary and sufficient conditions, suggesting that the nonrelativized solution to the question of this equivalence will be difficult to determine. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
