1. What is 1stOpt     1stOpt is a robust, flexible, easiest-to-use global optimization, nonlinear regression, equation solve and parameter estimation program with the start-of-the-art optimization a;gorithms. It is designed especially for general users to deal with the complicated jobs that are hard or impossible to be solved by regular/traditional approaches. Its intuitive, simple and friendly user-interface, straightforward operations and high efficient performance make it the most powerful tool for science and engineering study.     For more than 20 years research works of 7D-Soft, the core engine based on the innovative research outcomes of the Universal Global Optimization (UGO) algorithm has been developed. The UGO algorithm, unlike most of others, can solve the optimization problems without requiring users to give/guess the initial parameter values for carrying out the numerical optimization calculation, but with the initial value is given by 1stOpt randomly instead of user, then find the optimal solution through UGO algorithm. Take nonlinear regression as an example, the most famous software packages in this area such as Matlab, OriginPro, SAS, SPSS, DataFit, GraphPad, etc., all of them need the appropriate initial values of parameters provided or guessed by users for finding the correct optimal solution. If the initial value of the parameter is set incorrectly, then result is difficult to converge and it is impossible to get the correct answers finally. In practice, it is quite difficult to provide/guess the appropriate initial values of parameters for most users, especially when the amount of parameters is large, guess of initial start values would be a nightmare for users. With the superiors global optimization ability and strong fault tolerance, 1stOpt can achieve the correct result with random initial start value in most of cases (>90%). 2.

An Overview of Similar Software     Matlab, Mathematical, Maple and MathCAD have been recognized as the four major families of mathematical software today, in addition SAS, SPSS, Lingo/Lindo, etc., in the field of scientific computation, the software abroad is undoubtedly in a dominant position. Domestically, due to the lack of unique and effective technical theories and methods/algorithms, although there are a few mathematical software available on the market, compared with the above-mentioned software packages, the functions are far from each other, there is no competitive advantages in the market.     For optimization numerical computation, the algorithm is undoubtedly the key to decide the software is good or bad, especially the optimization algorithm is not only an important component of scientific calculation, but also the main support technology for artificial intelligence (AI). Looking at the scientific optimization computing areas today, 1)In the area of nonlinear curve fit and parameter optimization, the most commonly used algorithms are Levenberg-Marquardt and Simplex Method, both of them can be attributed to the local optimal method, as a result, how to effectively determine the initial start-values of the parameter to avoid trapping into the local optimal  is always difficult to overcome, due to this, some practical problems may never get correct solutions; 2)For other optimization problems, although there are many theoretically proven global optimization algorithms, such as genetic algorithms, simulated annealing, etc., in practical applications, these algorithms are inefficient and premature, and fall into local optimal solutions easily, in many cases, those kind of algorithms cannot fulfil requirements. 1stOpt, by virtue of its pioneering and revolutionary algorithm theory, is superior to any currently known software package in the field of optimization such as nonlinear fitting and parameter estimation. In addition, 1stOpt also performs well for problems that other software is difficult to solve, such as implicit function optimization problems, non-linear integer, mixed integer programming, and so on. 6. Test Comparison     Nonlinear Fitting Test: the nonlinear curve fit of 1stOpt is powerful than any other similar software package available today in the world, such as SPSS, SAS, Matlab, Origin, Systat, DataFit, etc. The greatest feature is that it is no long to need the end-user to provide or guess the initial start-values for each parameter, but randomly generated by itself, the probability for finding the correct solution is higher than any others. American National Institute of Standards and Technology (NIST) have a set of test dataset which include 27 nonlinear curve fit questions. Almost all of the data analysis software venders make those test data as their performance criteria. 1stOpt is the only software package that doesn't need the initial values provided by NIST compared with other software package and it can get all of the optimal solution with any random values (if use the initial values provided by NIST, it is more easier to find the optimal solution using 1stOpt). In practice, it is very difficult to choose a reasonable initial value group, especially in the case of a large number of parameters. In this sense, 1stOpt is in a leading place in curve-fitting area in the world.     Other Optimization Problems Test: due to the feature of "not require to provide/guess initial start-values", 1stOpt can get global optimization solutions more effectively and more higher accuracy than most others.       7.
