By worst-case efficient on-line we mean that the worst-case cost of adding an element is Theta(log n), n is the number of elements added so far. Second, we show how to maintain a binary search tree with an optimal height of exactly dlog(n + 1)e at an amortized cost of O(log ...
In this paper we describe an experimental study where we evaluated the practical efficiency of three worst-case efficient priority queues: 1) a weak heap that is a binary tree fulfilling half-heap... A Bruun,S Edelkamp,J Katajainen,... - International Conference on Experimental Algorithms 被...
Worst-Case InstanceAlgorithmSearch-based software engineering has mainly dealt with automated test data generation by metaheuristic search techniques. Similarly, we try to generate the test data (i.e., problem instances) which show the worst case of algorithms by such a technique. In this paper, ...
You might think the second approach would run more slowly, because a binary search requires the input be sorted. That’s true. But notice that the programmer of the antipattern forgot to break out of the loop when finding the match, so that code’s efficiency is terrible anyway. ...

aiT WCET Analyzers statically compute tight upper bounds for the worst-case execution time (WCET) of tasks in real-time systems. They directly analyze binary executables and take the intrinsic cache and pipeline behavior into account.Qualification run results Difference analysis Visualization of cache ...
In this paper, we evaluate the performance of a suboptimum maximum-likelihood receiver for FFH/BFSK systems with a worst case multi-tone jamming and additive white Gaussian noise over frequency selective Rician fading channel. As we know the computation of nonlinear modified Bessel function is requi...
