Euler’s problem, Euler’s method, and the standard map; or, the discrete charm of buckling - Domokos, Holmes - 1993 () Citation Context ...solutions for sheets compressed in a box can only be achieved by differently associating folds or by varying their length constraints. Actually, it ...
In the next graph, we see the estimated values we got using Euler's Method (the dark-colored curve) and the graph of the real solution y=ex/2y=ex/2 in magenta (pinkish). We can see they are very close. In this case, the solution graph is only slightly curved, so it's "easy"...
On a side note, the isPrime function here is very naive, and for later problems I started to use a sieve. which on my machine was able to generate all the primes under 1,000,000 in under a second. You might find it useful for some of the later prime number related problems too. S...
The Jameson and Mavriplis algorithm is a symmetrical second-order one, while the Liou and Steffen algorithm is a flux vector splitting first-order upwind one. Both schemes use a second-order Runge-Kutta method to perform time integration. The steady state problems of the supersonic flow along...
However, as I approached, I found the problems are not independent and many are closely related each other, so I reorganized the work and categorized the problems (and also solutions). After that, ah, doesn't it like a gallery, a space for my little programs, themed with the art of ...

Convergence of a step-doubling Galerkin method for parabolic problems We analyze a single step method for solving second-order parabolic initial-boundary value problems. The method uses a step-doubling extrapolation scheme in... BP Ayati,TF Dupont - 《Mathematics of Computation》 被引量: 39发表:...
and he read mathematics texts on his own and took some private lessons. Eulers father wanted his son to follow him into the church and sent him to the University of Basel to prepare for the ministry. He entered the University in 1720, at the age of 14, first to obtain a general educat...
