algorithm - Dijkstra's alghoritm second minimum way -


so have next task:find minimum , second minimum way(which can same) value in graph , use dijkstra's alghoritm. first minimum good(just use alghoritm) have problem finding second minimum.tried find way ,based on first minimum way, smallest difference that's isn't working because second minimum way can different first.so ideas on finding second minimum way?

assuming store distance in array distance[x] representing distance node x, can switch array matrix. so, every node x you'll have list of values stored in distance[x]. on, use of values compute distances node adjacent x. after finished, can select line destination node , pick second minimum value there.

c# - DevExpress.Wpf.Grid.InfiniteGridSizeException was unhandled -

when using devexpress, see error: devexpress.wpf.grid.infinitegridsizeexception unhandled message="by default, infinite grid height not allowed since grid rows rendered , hence grid work slowly. fix issue, should place grid container give finite height grid, or should manually specify grid's height or maxheight. note can avoid exception setting gridcontrol.allowinfinitegridsize static property true, in case grid run slowly." the problem dxgrid has infinite height. to fix, set height non-infinite. snoop absolutely invaluable this: if "height" xaml element infinite (i.e. 0 or nan ), can set using one of following: option 1: height="{binding path=actualheight, relativesource={relativesource mode=findancestor, ancestortype=uielement}}" option 2: verticalalignment="stretch" option 3: height="auto" hint: use verticalalignment="stretch" if child of grid <rowdefinition height=

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
