....for subconstant, indeed arbitrary, min entropy rate. However, thus far, it was only known how to optimize one of two parameters to within a constant factor, while paying a superconstant factor in the other. Constructions with seed length d = O(log n) for arbitrary min entropy were given in [26, 10, 17, 20], but the best output length achieved was m = k log k [17, 23] Constructions with output length The original definition of extractors in [14] is stronger than the one above (from [13] in that it requires the seed to be explicitly included in the output. Our constructions also imply such ....
....The task of extraction is made significantly easier given this additional structure of block sources. Indeed, good extractors for block sources are already known. Such extractors are called block source extractors. Based on the method for block source extraction of [14] and using newer extractors [16, 13, 10, 23, 20] it is possible to obtain a block source extractors that extract k1 bits using O(log n) long seed as long as k2 is at least poly log n (e.g. log n) Somewhere Random Sources. A central notion in our paper is that of a somewhere random source, as introduced by Ta Shma [13] Roughly speaking, a ....

.... resource bounded Kolmogorov complexity and derandomization techniques begun in [2, 3] We introduce nondeterministic time bounded Kolmogorov complexity measures (KNt and KNT) and examine the properties of these measures using constructions of hitting set generators for nondeterministic circuits [22, 26]. We observe that KNt bears many similarities to the nondeterministic distinguishing complexity CND of [8] This motivates the definition of a new notion of time bounded distinguishing complexity KDt, as an intermediate notion with connections to the class FewEXP.ThesetofKDt random strings is ....
....begun in [2, 3] in which recent progress in derandomization techniques is employed to provide new insights about resource bounded Kolmogorov complexity. One topic that was not discussed in the earlier papers is derandomization techniques for nondeterministic circuits, as provided by [22] and [26]. We will turn our attention to that task in Section 2, after first laying some groundwork by presenting our basic definitions. In the earlier papers [2, 3] we focused on notions of resource bounded Kolmogorov complexity, including Kt and KT. The first of these was originally defined and studied ....
