[eus] Azken urteetan euskararen ezagutza handiagotzen ari bada ere, erabilera gero eta murritzagoa da bai gizartean, bai eskolan. Lan honetan, D ereduko eskola bateko Haur Hezkuntzako 5 urteko gelako hizkuntza-erabilera ikertu da eta erabilera horretan eragin ditzaketen aldagaiak aztertu dira. Horretarako, ikasleei, irakasleari eta haurren familiei ARRUE proiektuan oinarrituriko zenbait galdetegi pasatu zaizkie. Horrez gain, haurren hizkuntza-erabilera neurtzeko behaketak ere egin dira egoera ezberdinetan (gela barruan eta gelatik kanpo irakasleekin, gela barruan ikaskideekin lanak burutzen, gela barruan ikaskideekin jolas librean eta jolastorduan ikaskideekin), informazio horiez baliatuz euskararen erabilera handitzeko neurriak hartu daitezen.

We present a scheme to generate clusters submodels with stage ordering from a (symmetric or a nonsymmetric one) multistage stochastic mixed integer optimization model using break stage. We consider a stochastic model in compact representation and MPS format with a known scenario tree. The cluster submodels are built by storing first the 0-1 the variables, stage by stage, and then the continuous ones, also stage by stage. A C++ experimental code has been implemented for reordering the stochastic model as well as the cluster decomposition after the relaxation of the non-anticipativiy constraints until the so-called breakstage. The computational experience shows better performance of the stage ordering in terms of elapsed time in a randomly generated testbed of multistage stochastic mixed integer problems.
