The multi-response optimization (MRO) problem in response surface methodology is quite common in applications. Most of the MRO techniques such as the desirability function method by Derringer and Suich are utilized to find one or several optimal solutions. However, in fact, practitioners usually prefer to identify all of the near-optimal solutions, or all feasible regions, because some feasible...

This paper presents a new heuristic for global optimization named low dimensional simplex evolution (LDSE). It is a hybrid evolutionary algorithm. It generates new individuals following the Nelder-Mead algorithm and the individuals survive by the rule of natural selection. However, the simplices therein are real-time constructed and low dimensional. The simplex operators are applied selectively...

An open-source data-analysis framework 2DMAT has been developed for experimental measurements of two-dimensional material structures. offers five analysis methods: (i) Nelder-Mead optimization, (ii) grid search, (iii) Bayesian (iv) replica exchange Monte Carlo method, and (v) population-annealing method. Methods through are implemented by parallel computation,which is efficient not only persona...

This study aims to review some applications of SIR model in COVID-19 epidemic situations, and tries simulate the predictions a specific country using R coding. article picks Nigeria as example, applying data from 28 February 31 May simulating infected cases with Coronavirus. Based on literature about usage this epidemic, current trend is focusing optimization parameters algorithm. As consequenc...

In this paper, we address the calibration of a family magnetic manipulation systems composed several coils that are moved around by serial robot manipulators. We show in paper whole system ultimately results calibrating manipulator and coil separately up to an unknown rigid transformation. For coil, propose use model has not been used so far literature; control-oriented which is sufficiently ac...

We propose a novel estimation method of the rotational velocity of a flying ball as well as its position and translational velocity via aerodynamics model by measuring the ball trajectory using the middle speed cameras for table tennis system. The aerodynamics model is complex nonlinear and the measured data of the ball trajectory has quantization errors because the size of the ball is very sma...

Block motion estimation can be regarded as a function minimization problem in a finite-dimensional space. Therefore, fast block motion estimation can be achieved by using an efficient function minimization algorithm instead of a predefined search pattern, such as diamond search. Downhill simplex search is an efficient derivative-free function minimization algorithm. In this paper, we proposed a...

The paper addresses tlie design of tlie polyphase IIR filters based on the “’-order single-coefficient allpass sub-filters in the constraint coefficient space using the Constraint Dowdiill Simplex Algorithm. Incorporating the bit-flipping algorithm into its core engine allowed the optitilisation routine to converge to better target designs without affecting tlie Iiigli speed of tlie original al...

A water budget analysis shows that under current conditions there is a 10% chance live storage in Lakes Mead and Powell will be gone by about 2013 and a 50% chance it will be gone by 2021 if no changes in water allocation from the Colorado River system are made. This startling result is driven by climate change associated with global warming, the effects of natural climate variability, and the ...
