Variations of Forward-SBNDM
نویسندگان
چکیده
Forward-SBNDM is a recently introduced variation of the BNDM algorithm for exact string matching. Forward-SBNDM reads a text character following an alignment of the pattern. We present a generalization of this lookahead idea and apply it to SBNDMq for q ≥ 3. As a result we get several new variations of SBNDMq. We introduce a greedy skip loop for SBNDM2. In addition, we tune up our algorithms and the reference algorithms with 2-byte read. According to our experiments, the best of the new variations are in several cases faster than the winners of recent algorithm comparisons.

String matching with lookahead
Forward-SBNDM is a recently introduced variation of the BNDM algorithm for exact string matching. Forward-SBNDM inspects a 2-gram in the text such that the first character is the last one of an alignment window of the pattern and the second one is then outside the window. We present a generalization of this idea by inspecting several lookahead characters beyond an alignment window and integrate...
متن کاملAn Adaptive Approach to Increase Accuracy of Forward Algorithm for Solving Evaluation Problems on Unstable Statistical Data Set
Nowadays, Hidden Markov models are extensively utilized for modeling stochastic processes. These models help researchers establish and implement the desired theoretical foundations using Markov algorithms such as Forward one. however, Using Stability hypothesis and the mean statistic for determining the values of Markov functions on unstable statistical data set has led to a significant reducti...
متن کاملPower Allocation Strategies in Block-Fading Two-Way Relay Networks
This paper aims at investigating the superiority of power allocation strategies, based on calculus of variations in a point-to-point two-way relay-assisted channel incorporating the amplify and forward strategy. Single and multilayer coding strategies for two cases of having and not having the channel state information (CSI) at the transmitters are studied, respectively. Using the notion of cal...
متن کاملPhotometric Stabilization for Fast-forward Videos
Videos captured by consumer cameras often exhibit temporal variations in color and tone that are caused by camera autoadjustments like white-balance and exposure. When such videos are sub-sampled to play fast-forward, as in the increasingly popular forms of timelapse and hyperlapse videos, these temporal variations are exacerbated and appear as visually disturbing high frequency flickering. Pre...
متن کاملEnhancing Working Memory Capacity in Persian Cochlear Implanted Children: A Clinical Trial Study
Introduction: Sensory deprivations such as hearing impairment that affect sensory input have a secondary impact on cognitive functions such as working memory (WM). WM capacity is an important cognitive component that processes language-related activities. Moreover, several studies have shown a deficit in WM in children with a cochlear implant (CI). We aimed to assess the performance of children...
