The relation of two patterns with comparable languages,t results that it is true only for very restricted patterns (with variables only) and only when erasing substitutions are considered. The relation between two patterns is studied also in the case that the languages they produce are equal.DEMN 发表于 2025-3-23 22:37:55

On the construction of optimal time adders,f multiplexer cells is used in the carry computation part. We show that, for the complete conditional carry adder, this results in an overall computation time which seems to be substantially shorter than for any other known (optimal time) adder (e.g. carry look ahead adders () or conditional s最有利 发表于 2025-3-24 15:08:01
On computations with integer division,ts. We characterize the families of languages L ⊂ ℕ that can be recognized over {+, −, DIV.}, {+, −, DIV}, and {+, −, *, DIV}, resp. and show that they are identical. Furthermore we prove lower bounds for CT‘s with operations {+, −, DIV.} for languages L ⊂ ℕ which only contain short arithmetic progrInfuriate 发表于 2025-3-24 22:20:21
Maintaining range trees in secondary memory, memory. To this end, we have to partition range trees into parts that can be stored in consecutive blocks in secondary memory. A number of partition schemes will be presented that limit the part sizes and the number of disk accesses necessary for performing updates and queries. Matching lower bound贪婪地吃 发表于 2025-3-25 00:14:38
