data structures - How to test efficiently Dijkstra algorithm -


i working on existing implementation of dijkstra , 1 of deliverable test whether implementation efficient solution issue @ hand or recommend alternate algorithm. question is... how should baseline existing dijkstra algorithm compare alternate? narrow scope, client using dijkstra dynamically chose best tariffs plan b2b consumers. make sense?

dijkstra algorithm find shortest path in graph. test , see how effective that, need compare other algorithms. bellman–ford algorithm, a* search algorithm , etc.

important notes

other performance, there other important issues dijkstra doesn't work negative values. why bellman-ford has been used instead in many problems.

also, dijkstra has different implementations.

dijkstra's algorithm list o(v 2) while dijkstra's algorithm modified binary heap o((e + v) log v) , dijkstra's algorithm fibonacci heap o(e + v log v). bellman–ford algorithm o(ve).

conclusion

if need see 1 better work, first see parameters matters , compare ones can suitable. if want, can test them since have been implemented other people before. need give them graph

Image
i trying repurpose pre-existing theme, includes drop down menu displays image. trying embed thinglink drop down menu's content section, not visible until resize browser window. here menu looks like: then when clicked, can see empty space image should show: then when browser resized, image appears: this code content of menu: <div class="ajax_accordion_content" style="display: none;"> <div class="report-detail"> <table border="0" cellpadding="0" cellspacing="0" width="100%" class="table_basic"> <tbody> <!-- thinglink image embedded --> <img style="max-width: 100%;" src="http://cdn.thinglink.me/api/image/832705713204625409/1024/10/scaletowidth#tl-832705713204625409;1043138249'" class="alwaysthinglink"/> <script async charset="utf-8" src="http://cdn.thinglink.me/jse/embed.j

i'm trying figure out way mean stack application keep track of users have paid grant them access portion of webpage. i've considered several options: stripe customer id, mongodb record, , html attribute can update. my mean stack keeps track of users jwt, , appears stripe assigns them own customer id isn't ideal. can done jwt opposed forced cutomer id? mongodb record. i'm thinking might best option. when new user has been created, i'll give attribute of haspaid = no. update record of customer when payment submitted. guess run script set unpaid each day? html element/attribute. don't know if possible; cool create key carried during html session after payment received. if person closers browser session closed? i'm looking guidance on 3 options determine if they're best solution. also, if has suggestions alternatives, i'm ears! thanks in advance. speaking generally, common approach second one: use attribute in data model indicates
