A web crawler stores fixed length representations of document addresses in a buffer and a disk file, and optionally in a cache. When the web crawler downloads a document from a host computer, it identifies URL's (document addresses) in the downloaded document. Each identified URL is converted into a fixed size numerical representation. The numerical representation may optionally be systematically compared to the contents of a cache containing web sites which are likely to be found during the web crawl, for example previously visited web sites. The numerical representation is then systematically compared to numerical representations in the buffer, which stores numerical representations of recently-identified URL's. If the representation is not found in the buffer, it is stored in the buffer. When the buffer is full, it is ordered and then merged with numerical representations stored, in order, in the disk file. In addition, the document corresponding to each representation not found in the disk file during the merge is scheduled for downloading. The disk file may be a sparse file, indexed to correspond to the numerical representations of the URL's, so that only a relatively small fraction of the disk file must be searched and re-written in order to merge each numerical representation in the buffer.

Methods of performing link adaptation in a wireless communication system for simultaneous transmission of codewords include selecting initial modulation and coding scheme (MCS) levels for the codewords, estimating a size ratio of the codewords, determining a number of scheduling blocks (SB) for the codewords with the initial MCS levels, and determining revised MCS levels for the codewords in response to the determined number of SBs. Transport block sizes are computed for the codewords, and it is determined if there is a need to increase the number of scheduling blocks in at least one of the codewords. If there is a need to increase the number of scheduling blocks in a codeword, scheduling blocks are added to the codeword, and the transport block size for the codeword is recomputed. The codewords are then simultaneously transmitted over different multiple input-multiple output (MIMO) communication channels using the same time and frequency resources.
