A Bench Mark Experiment for Minimization Algorithms
In this paper we suggest a single bench mark problem family for use in evaluating unconstrained minimization algorithms or routines. In essence, this problem consists of measuring, for each algorithm, the rate at which it descends an unlimited helical valley. The periodic nature of the problem allows us to exploit affine scale invariance properties of the algorithm. As a result, the capacity of...
متن کاملHigh level Ab inito bench mark computaions on weak interactions (H2)2 dimer revisited
The Potential Energy Surface PES of (H2)2 dimer has been investigated, using five simple rigid rotor models. These models are called: head to head, symmetric side to side, L , steplike and T model. All calculations were done at two levels of ab initio methods: MP2(Full) and QCISD (T,Full) using cc-pVTZ basis set at singlet state of spin multiplicity. The results of scanning PES were then fitte...
متن کاملContemporary Bench Mark Techniques in Fractal image Compression-A Survey
Fractal Image Compression (FIC) is a extremely improving modern technique in the field of data and image compression; it is based on representing an image with affine contractive transform using features of self-similarity found in the image. This technique in recent time has achieved intense recognition because of its desirable advantages like very high compression ratio (C.R), high decoding s...

متن کاملSolar Light Photocatalytic CO2 Reduction: General Considerations and Selected Bench-Mark Photocatalysts
The reduction of carbon dioxide to useful chemicals has received a great deal of attention as an alternative to the depletion of fossil resources without altering the atmospheric CO2 balance. As the chemical reduction of CO2 is energetically uphill due to its remarkable thermodynamic stability, this process requires a significant transfer of energy. Achievements in the fields of photocatalysis ...
