Given the following code: for (int i = 0; i < 100; i++) { myFunction(Color(1.f, 1.f, 0.f)); } The constructor of Color would be called 100 times, although it always evaluates to the same thing every time and myFunction does not create a copy (utilizing const Color&). I have already taken the necessary steps to ..

How to optimise this code to reduce time complexity?It works but some test cases are getting time limit exceed error. Please help me to reduce the time complexity ? int minimumCost(int n,int m,vector<vector<int>>teams){ sort(teams.begin(),teams.end(),[&](const vector<int>& a,const vector<int>& b)-> bool{ if(a[1]==b[1]){ return a[0]<b[0]; } return a[1]<b[1]; }); long long dp[m]; for(int i=0;i<teams.size();i++){ bool f=false; int g=teams[i][1]-teams[i][0]+1; ..

I got a way to develop MultiStart using lsqcurvefit in Matlab. F = @function problem = createOptimProble(…) ms = MultiStart(…) [T_multi, T_error] = run(…) Is there any way or idea to do it in C++? Source: Windows Que..

Problme: I won’t get the result that I get from Matlab implementation, I am not sure pow_pos(norm(x(:, 1) – start’), 2) I have converted correctly, here is the converted code Variable::t x_0 = Var::vstack(x->index(0, 0), x->index(1, 0), x->index(2, 0)); M->constraint(Expr::vstack(t_tmp->index(0), Expr::sub(x_0, start_)), Domain::inQCone()); M->constraint(Expr::hstack(t->index(0), 1, t_tmp->index(0)), Domain::inPPowerCone(1.0/2)); Here is the original code I wrote in ..

class classN { public: bool operator== (const classN &o) const {//some logic here}; bool operator!= (const classN &o) const {return !(*this == o);}; }; I see this as the best way to write overloads of operator== and operator!=, as I need to change code only once. however, I’ve seen in different projects people writing actual ..

I have a set of constraints in the following way, yet could not formulate it properly. In the following way, I could take the norm, but how can we get its power? Model::t M = new Model(); auto start_ = new_array_ptr<double, 1>({-4, 0, 2}); auto x_0 = M->variable(new_array_ptr<int,1>({3, 1}), Domain::unbounded()); M->constraint(Expr::vstack(t->index(0), Expr::sub(x_0, start_)), Domain::inQCone()); If ..

I am having a strange error still could not figure it out. #include <iostream> #include "fusion.h" using namespace mosek::fusion; using namespace monty; int main(int argc, char ** argv) { int number_of_steps = 7; int lambda1 = 1000; int lambda2 = 1000; int dim_space = 3; auto A = new_array_ptr<double, 2>({ {-0.1504 , 0.5675 , -0.7252}, ..
