How to identify triangles in Netlogo -

-

how can find triangles in undirected network in netlogo, is, list instances of a-b, b-c, c-a?

thank you,

thomas

here naive approach. if network not big, enough:

to-report find-triangles   let triangles (list)   ask turtles [     let t1 self     ; find triangles turtle part of     ask link-neighbors [       let t2 self       ask link-neighbors [         let t3 self         if link-with t1 != nobody [           set triangles lput (turtle-set t1 t2 t3) triangles         ]       ]     ]   ]   report remove-duplicates triangles end

let's test simple network:

to setup   clear-all   create-turtles 4   ask turtle 0 [     create-link-with turtle 1     create-link-with turtle 2   ]   ask turtle 1 [     create-link-with turtle 2       ]   ask turtle 3 [     create-link-with turtle 1     create-link-with turtle 2   ]   ask turtles [ set label ]   repeat 30 [ layout-spring turtles links 0.2 5 1 ]   show map sort find-triangles end

from command center, result is:

observer> setup observer: [[(turtle 1) (turtle 2) (turtle 3)] [(turtle 0) (turtle 1) (turtle 2)]]

i have following code almost works properly; private void cbstatus_drawitem(object sender, listboxdrawitemeventargs e) { string item = e.item string; if (item != null) { switch (item) { case "1": e.appearance.forecolor = color.green; e.appearance.backcolor = color.green; break; case "2": e.appearance.forecolor = color.orange; e.appearance.backcolor = color.orange; break; case "3": e.appearance.forecolor = color.red; e.appearance.backcolor = color.red; break; } } } when dropdown shown, items forecolor correct, backcolor remains whatever backcolor of theme is; i.e. if i've got set dark theme, backcolor dark, cells in gridview, rather being green/orange/red. i've tried setting e.appearance.options.usebackcolor trying set e....
