python - Better way to calculate λ in a Poisson distribution if the ...
@sierra_papa For the Poisson, P{X=x} = lambda^x * exp(-lambda) / x!.When x=0 we have that both lambda^x and x! are 1, so it reduces to just the single exponential term and yields the closed-form solution John Coleman & I came up with. Things don't break as cleanly for any case other than P{X=0}, and you're left with lambda as both a base and a power. For example, when x=1 you have to solve lambda * exp(-lambda) = p.At that point I think you're stuck with solving it numerically with root ...

Regular Languages | Brilliant Math & Science Wiki
A regular language is a language that can be expressed with a regular expression or a deterministic or non-deterministic finite automata or state machine. A language is a set of strings which are made up of characters from a specified alphabet, or set of symbols. Regular languages are a subset of the set of all strings. Regular languages are used in parsing and designing programming languages and are one of the first concepts taught in …
