I will post here the output of two commands that has me a bit worried. Of course it is entirely possible that I am overlooking something very simple, which is why I am writing to your site.

Some errors in MapleSim Tutorials! While I was working with MapleSim tutorials, I have encountered some problems that the results did not match the answer. I have uploaded the files, that I have worked on, in a zip file to this address (http://www.mediafire.com/download/2pirvfbawyjfa18/MapleSim_Projects.zip). The problems are as follows:
1. Based on video tutorial on this page (
On May 17, 2013 I finished a 2,000,000 or more digit computation of the MRB constant, using only around 10GB of RAM. It took 37 days 5 hours 6 minutes 47.1870579 seconds. You can write firstname.lastname@example.org for the digits.
The program I used was based on Richard E. Crandall's work:
Richard E. Crandall, Unified algorithms for polylogarithm, L-series, and zeta variants (53 pages)
I would like to pay attention to http://www.ams.org/samplings/feature-column/fc-2013-05 .
Comparing the Galileo's calculation 87654/53 with the capacity of Maple, the question arises:
"Are we cleverer than Galileo Galilei?". I don't know the answer.
The purpose of this post is the investigation of the connection between the connectivity of an undirected graph and the numbers of its vertices and edges with help of the GraphTheory package.
The reader is referred to http://en.wikipedia.org/wiki/Graph_theory and to ?GraphTheory for info.
Using the Quandl API, we have created a Quandl library for Maple. The Quandl library for Maple provides easy access to Quandl’s repository of over 5 million time-series datasets from directly inside Maple, allowing you to utilize Maple’s robust tools for mathematical statistics and data analysis on Quandl’s extensive collection of data. This library features a similar set of functionalities to the Quandl
We have just released a new, more powerful version of the Maple Global Optimization Toolbox.
For this new release, Maplesoft has partnered with Noesis Solutions to develop a new version of the Maple Global Optimization Toolbox that is powered by Optimus technology. Optimus, from Noesis Solutions, is a platform for simulation process integration and design optimization that includes powerful optimization algorithms. This advanced technology is now available...
An intersection in my neighbourhood, currently controlled by a 2-way stop, is under consideration to become a 4-way stop. This means the traffic that currently has the right-of-way will be required to come to a complete stop, wheras previously they could have coasted down the hill, and accelerated up the other side. Politics aside, I was curious to explore the following question:
It's interesting that every continuous piecewise linear function can be specified by one explicit equation with absolute values. The procedure JoggedLine carries out such conversion.
Formal arguments of the procedure:
A - a list of the coordinates of the vertices of the polyline or the continuous piecewise linear expression defined on the entire real axis.
B (optional) - a point on the left "tail"...
Here an example of integral that Maple 17 cannot calculate (mean of standard Gumbel distribution)
> G:=int(x*exp(-x)*exp(-exp(-x)), x = -infinity .. infinity);
The result is known as the Euler-Mascheroni constant as shown by a numerical computation:
> identify(%, extension = [gamma]);
Also, it cannot compute the variance
As described on the help page ?updates,Maple17,Performance, Maple 17 uses a new data structure for polynomials with integer coefficients. Our goal was to improve the performance and parallel speedup of polynomial algorithms that underpin much of the system and create a platform for large scale polynomial computations. Shown below is the new representation for 9xy3z
My site of Russian Maple's Center (webmath.exponenta.ru) reached the milestone of 8000000 visits.
Year of foundation - 2000
Now - 8,000 visitors a day.
Since the Maplesoft is not interested in this project, I renamed it.
Current title: Site of Independent Work of students.
I wish you all good luck!
