Using Markov Chains To Design Algorithms For Bounded-Space On-Line Bin Cover
نویسندگان
چکیده
We show how the on-line bounded-space bin cover problem can be modeled with a Markov chain. We then use this Markov chain formulation to derive an algorithm for the on-line bounded-space bin cover problem. Our algorithm is designed to perform well in a restrictive environment where it can utilize only very few open bins at each time. We analyze the performance of our algorithm and compare it to the Sum-of-Squares with Threshold algorithm. The experimental results show that our algorithm compares favorably with the Sum-of-Squares with Threshold algorithm, and the average waste incurred by our algorithm is very small even when it is forced to use only a handful of open bins.

Bounded-space online bin cover
In this paper, we look at the online bounded-space bin cover problem and show how we can use the language of Markov chains to model and analyze the problem. We will use the insights given by the Markov chains to design an algorithm for the online bounded-space bin cover problem. The algorithm is a heuristic that we create by simplifying the Markov chain. We also show how we can use simple metho...
متن کاملStochastic Dynamic Programming with Markov Chains for Optimal Sustainable Control of the Forest Sector with Continuous Cover Forestry
We present a stochastic dynamic programming approach with Markov chains for optimal control of the forest sector. The forest is managed via continuous cover forestry and the complete system is sustainable. Forest industry production, logistic solutions and harvest levels are optimized based on the sequentially revealed states of the markets. Adaptive full system optimization is necessary for co...
متن کاملEvaluation of First and Second Markov Chains Sensitivity and Specificity as Statistical Approach for Prediction of Sequences of Genes in Virus Double Strand DNA Genomes
Growing amount of information on biological sequences has made application of statistical approaches necessary for modeling and estimation of their functions. In this paper, sensitivity and specificity of the first and second Markov chains for prediction of genes was evaluated using the complete double stranded DNA virus. There were two approaches for prediction of each Markov Model parameter,...
متن کاملImproved Space for Bounded-Space, On-Line Bin-Packing
The author presents a sequence of linear-time, bounded-space, on-line, bin-packing algorithms that are based on the "HARMONIC" algorithms Hk introduced by Lee and Lee [J. Assoc. Comput. Mach., 32 (1985), pp. 562-572 ]. The algorithms in this paper guarantee the worst case performance of Hk, whereas they only use O(log log k) instead ofk active bins. For k >_6, the algorithms in this paper outpe...
متن کاملThe Rate of Rényi Entropy for Irreducible Markov Chains
In this paper, we obtain the Rényi entropy rate for irreducible-aperiodic Markov chains with countable state space, using the theory of countable nonnegative matrices. We also obtain the bound for the rate of Rényi entropy of an irreducible Markov chain. Finally, we show that the bound for the Rényi entropy rate is the Shannon entropy rate.
