I could be perceived as biased since I'm the CTO of Evolved Analytics (www.evolved-analytics.com) and wrote much of the DataModeler code over the past 13 years, however, DM is probably the most efficient, complete and powerful symbolic regression platform out there for any environment. In addition to the basic model development, it supports the entire ...

Since nobody answered this question, I did research by myself. IMO, the best available free Mathematica for Lie Algebras is LieART (version 1.0.1) which includes all the exceptional Lie Algebras and a lot more (like branching rules), and is quite natural to use. The latex package included (lie art.sty) generates some conflicts when compiled with Latex but ...

According to Oleksandr R. wmic can only be run by Administrators. Here is how you get the Serial on Windows. Import["!wmic bios get serialnumber", "Text"] To get CPU information Import["!wmic cpu get NumberOfCores, NumberOfLogicalProcessors/Format:List", "Text"] To get the MAC Address run. StringSplit[ StringReplace[ StringCases[Import["!ipconfig /...

I have this hope that Mathematica 10 will make the efforts in my NashEquilibriaIn33Games Demonstration seem extremely primitive and that it will directly implement a good chunk of game theory. I think it's time for Wolfram Research to take the leap into this now well-established area of Math/Econ/Biology, etc. The work being done in algorithmic game theory ...

Sorry about this, I was under the impression the CPC library was available to everybody. I tried to upload the code to arXiv but it didn't work, so the Mathematica package and a tutorial notebook can now be found on ResearchGate or github. Hopefully I can set up a more convenient spot for people to download the package soon.

Wolfram has renamed the LogLikelihood function in the Time Series package to LogLikelihoodFunction. But they have apparently forgotten to update the documentation.

The only thing I could find very easily is the HWaddr of the network device that can be obtained by SystemInformation["Network", "IPAddresses"]

Just heard back from David Harrison, who is the creator of the package. He says EDA is compatible with Mathematica 11. According to him, the compatibility is not advertised because he has not gotten around to updating the documentation. Edit: I can confirm that it works wonderfully.

You should check out the OutputType option, which allows you to specify Graphics output instead of the default Optical System output from functions like AnalyzeSystem, DrawSystem, and ShowSystem. mySystem = DrawSystem[{ConeOfRays[20, NumberOfRays -> 7], RefractiveIndex[1.5], Polarization[45], Ray[WaveLength -> .45, AddTo -> NewRay], ...

I finally found where to download this package. http://cpc.cs.qub.ac.uk/summaries/AEQN_v1_0.html But it is free only if your institution is a subscriber to Elsevier's Computer Physics as Sjoerd C. de Vries mentioned above.

Have you looked at demonstrations.wolfram.com/NashEquilibriaIn33Games and the linked sources? It relies on formulae and solution methods from Hal Varian's 1996 book "Computational Economics and Finance: Modeling and Analysis with Mathematica" (which I have had on my Amazon wish list for years but have never gotten around to buying.) The sample notebooks ...

After some research I've found this partial solution: Step 1: Open Excel (if you have it!) Step 2: Open Excel Link Needs["ExcelLink"] Step 3: If you don't have any DDE Link for Excel, simulate real time data using Dynamic[Refresh[Excel["B1"] = RandomInteger[100], UpdateInterval -> 1]] Step 4: Import back to Mathematica your simulated data a = ...

I think you really want $-\pi\leq \Im(z) \leq \pi$. Then let the Presentations function ComplexMap do the work for you! << Presentations strip = ComplexRegionDraw[0 <= Re[z] <= 1, {z, -2 - Pi I, 2 + 4 Pi I}]; domain = Draw2D[{Opacity[0.6], strip}, Frame->True, Axes->True, PlotRange->2, FrameLabel->{Re, Im}, PlotLabel-&...

Changing the Excel macro argument type from String to Variant resolved the error: Sub macro1(str As Variant) Range("A1").Value = str End Sub

The Variance Problem Find $Var(Z)$, where: $$Z = \begin{cases}W + X_1 & \text{if } W \leq c \\ W + X_2 & \text{if } W > c \end{cases}$$ where $\quad W \sim N(\mu_0, \sigma_0^2), \quad X_1 \sim N(\mu_1, \sigma_1^2), \quad X_2 \sim N(\mu_2, \sigma_2^2)$ are independent, and $c$ is a constant. Solution Let $f(w, x_1,x_2)$ denote the joint pdf ...

I have come very late to this party, but maybe you would like to check out Paul Knysh's "sym" package on GitHub. I played a bit with it today using Mma 11.0. The code definitely runs; however, I did not run extensive searches because I was afraid of melting my MacMini :-).
