Probabilistic Performance Forecasting for Unconventional Reservoirs With Stretched-Exponential Model

Valko, Peter P. (contributor) - 2011

Reserves estimation in an unconventional-reservoir setting is a daunting task because of geologic uncertainty and complex flow patterns evolving in a long-stimulated horizontal well, among other variables. To tackle this complex problem, we present a reserves-evaluation workflow that couples the...

John Doe's old-age provision: Dollar cost averaging and time diversification

Ulbricht, Dirk - 2014

Do timing and time diversification improve the average investor?s stock market return? Contrary to literature?s scenario of wealthy investors, average investors invest each month over life. Many purchases prevent investors from buying at peak, but horizons decrease, giving latter investments...

Binary classification via spherical separator by DC programming and DCA

Thi, Hoai Le; Le, Hoai; Dinh, Tao Pham; Huynh, Ngai Van - In: Journal of Global Optimization 56 (2013) 4, pp. 1393-1407

into the DC (Difference of Convex functions) programming framework and solved by DCA (DC Algorithm) as shown in the works … is to investigate more attractive DCA based algorithms for this problem. We consider a new optimization model and propose … two interesting DCA schemes. In the first scheme we have to solve a quadratic program at each iteration, while in the …
