i'm looking efficient way split array chunks have similar histogram. for example, given array: l = np.array([1, 2, 3, 4, 1, 1, 1, 2, 3, 4, 55, 5, 5, 5, 5, 5, 3, 2, 2, 21, 2]) i obtain: c1 = np.array([1, 4, 1, 5, 5, 3, 2]) c2 = np.array([2, 1, 3, 4, 5, 5, 2]) c3 = np.array([3, 1, 2, 55, 5, 2, 21]) not each chunk should have similar size , similar sum on given function f: 1. |sum(ci, f) - sum(cj, f)| < e, != j 2. |len(ci) - len(cj)| < e, != j where sum(c, f) = f(c[0]) + ... + f(c[len(c)]) edit: clarify intention of this. want parallelize process on list n sub-processes cost has distributed among each sub-process evenly. cost of processing element in list function f of integer @ same position in array l , f computational complexity of process. example, f(i)=i^2 . so, want processes have same computational cost , not have processes finish while others last forever. let's start weak assumption similar histograms defined in following rudimenta...

one main , obvious meaning, found in standard library - "initializing collection list of elements": std::vector<int> v = {1, 2, 3}; another meaning can found behind link on std::bitset below - "the single value assembled elements of initializer_list". the third example in standard library std::piecewise_constant_distribution, hesitate semantic has, not collection of elements. what other use cases std::initializer_list constructors? if possible, examples real code. it's question class design. because of pecularities of list-initialization adding std::initializer_list constructor existing class can easily surprisingly breaking change , when writing new class should know in advance if ever need std::initializer_list constructor. so, i'm trying simulate ability see future writing out use cases std::initializer_list constructors. the primary question is: how determine class have (not surprising users) std::initializer_list constructors in...

i have asp.net page this: protected sub page_load(sender object, e system.eventargs) handles me.load 'page load code here. call service layer, calls business layer. end sub protected sub button1_click(sender object, e system.eventargs) handles button1.click 'button code here end sub the code in page_load takes long because has connect lots of different databases (code contained in business layer). best way cache page code in page_load not run before click event? code in page_load required generates controls. button1_click loops through these controls. i tend focus on business layer , data layer. realize basic question. page_load run before click event. need familiarize asp.net page lifecycle model , how postbacks work. most of code runs in page_load shouldn't run again on postback, use if statement check if it's postback. loading of controls etc update viewstate , wont necessary reinitialize on postback.

was reading this answer , surprised me, suggestion must always call base class constructor in derived class constructor. if working default constructors, consider: class bar : public foo { private: int y; public: bar() : foo(), y(0) { } ... is call foo() necessary here? you not need explicitly call base class constructor in constructor, in case compiler implicitly calls default constructor, or compile-time error, if none callable. same applies members non-pod. an alternative member initialiser list only consisting of delegation constructor of class, creating delegating constructor.
