A novice Mathematica user exploring Mathematics and Mathematica. Tuesday, February 28, 2012. This is a an illustrative demonstration of from the puzzle. I did this with little time. Options such as animating the rock, illustrating the effect of different densities of rock or object, e.g. floating objects and changing to assess and quantify the change are all options (a low priority on a CDF todo list).

A Novice experiments with Mathematica. Why Some Say The Moon. Why Some Say The Moon. June 22, 2015. It has been a challenging time recently and I have been plagued by ill health…in spare time I have been musing with. I still vividly remember watching the lunar landing on a black and white television…despite the grainy image and the staccato noisy audio I was transfixed. Leave a Reply Cancel reply.

Mathematica bits: Magic Square
http://mathematica-bits.blogspot.com/2011/01/magic-square.html
Tips for Mathematica users. Sunday, January 2, 2011. Here's an interesting tidbit I saw linked. From reddit - the following decimal expansions form a magic square. Here's how you'd check the row and column sums. Row[k ] := PadLeft[IntegerDigits[Floor[k/(v 1)*10 v] , v];. Mat = row /@ Range[v];. Posted by Yaroslav Bulatov. October 4, 2014 at 12:04 PM.

Mathematica bits: Semidefinite programming in Mathematica using CVXOPT
http://mathematica-bits.blogspot.com/2011/03/semidefinite-programming-in-mathematica.html
Tips for Mathematica users. Thursday, March 3, 2011. Semidefinite programming in Mathematica using CVXOPT. One can get access to semidefinite programming from Mathematica by using Pythonika to interface with Python's cvxopt package. For MacOS 10.6 and Mathematica 8 the following should work. Install 64-bit Python 2.7 distribution from official site. Get latest cvxopt sources. Fill correct paths in Pythonika Makefile, also add "-lstdc -framework CoreFoundation" linker flags. G = GridGraph[{4, 3}];. Gram =...

Mathematica bits: Independence Polynomials with Tree Decomposition
http://mathematica-bits.blogspot.com/2011/01/independence-polynomials-with-tree.html
Tips for Mathematica users. Saturday, January 8, 2011. Independence Polynomials with Tree Decomposition. A lot of NP-hard problems on graphs become easy if you find a good tree decomposition. Essentially, tree decomposition asks for a way to take a set of small sets of vertices and connect them in a way so that vertices shared by any pair of connected sets is a separator of the graph. Two examples below show a graph on the left and it's optimal tree decomposition on the right. Posted by Yaroslav Bulatov.

Mathematica bits: Making cross-words with Mathematica
http://mathematica-bits.blogspot.com/2011/02/making-cross-words-with-mathematica.html
Tips for Mathematica users. Wednesday, February 2, 2011. Making cross-words with Mathematica. A recent question on Stack Overflow. Asked how to use Mathematica to find a complete grid of words like this. Each row and each column must be a valid word. A notebook below gives a way to solve this for small grids using SAT solver, and another answer in the post gives a pattern-based approach. Posted by Yaroslav Bulatov. October 4, 2014 at 11:53 AM.

Mathematica bits: Cluster variation method example
http://mathematica-bits.blogspot.com/2011/02/cluster-variation-method-example.html
Tips for Mathematica users. Monday, February 7, 2011. Cluster variation method example. Cluster variation methods for search work by approximating the distribution over satisfying instances, and then using marginals of that distribution to guide the search. Here's an animation of occupation probability marginals with lambda going from 0 to 3. You can see the mass gets concentrated on nodes that are part of the largest independent set in the graph, at which point you can use greedy search. Can you help me?
