Fibonacci, Binary, or Binomial heap in c#?

Are there any heap data structure implementations out there, fibonacci, binary, or binomial? Reference: These are data structures used to implement priority queues, not the ones used to allocate dyn…


algorithm - How can I efficiently calculate the binomial cumulative distribution function?

Let's say that I know the probability of a "success" is P. I run the test N times, and I see S successes. The test is akin to tossing an unevenly weighted coin(perhaps heads is a success, tails is…


java - Algorithm to generate Poisson and binomial random numbers?

i've been looking around, but i'm not sure how to do it. i've found this page which, in the last paragraph, says: A simple generator for random numbers taken from a Poisson distribution is obtained us…


c++ - Calculating Binomial Coefficient(nCk) for large n & k

I just saw this question and have no idea how to solve it. can you please provide me with algorithms,C++ codes or ideas? This is a very simple problem. Given the value of N and K, you need to tell…


algorithm - Real world applications of Binary heaps and Fibonacci Heaps

What are the real world applications of Fibonacci heaps and binary heaps? It'd be great if you could share some instance when you used it to solve a problem. Edit: Added binary heaps also. Curious to…


Efficient Method for Calculating the Probability of a Set of Outcomes?

Let's say I'm playing 10 different games. For each game, I know the probability of winning, the probability of tying, and the probability of losing(each game has different probabilities). From thes…


Haskell: Equation Expander 1+(1+(1+(1+(…))))=∞

Does there exist a equation expander for Haskell? Something like foldr.com: 1+(1+(1+(1+(…))))=∞ I am new to Haskell I am having trouble understanding why certain equations are more preferable than oth…


Estimating Weibull density parameters(error: “…initial value in 'vmmin' is not finite”)

I am trying to estimate the shape and scale of a data set. I used two different ways and for both I got an error message: First, I tried by moments using the survey package: survreg(Surv(all.ws)~1…


algorithm - What is the difference between binary heaps and binomial heaps?

I need to know the main difference between binary and binomial heaps regardless of the their structure difference that binary heaps can have only two child(tree representation) and binomial heaps can…



numpy arbitrary precision linear algebra

I have a numpy 2d array[medium/large sized-say 500x500]. I want to find the eigenvalues of the element-wise exponent of it. The problem is that some of the values are quite negative(-800,-1000, e…
