c# - BotFramework on Skype For Business does not authenticate -


we developing bot using bot framework (microsoft bot builder 3.9 on vs2017), calling luis , qna maker apis , want deploy on skype business online. using bot framework emulator (no ngrok used), works on development environment (localhost).

we have published api on local server (intranet) , exposed through azure gateway, test api endpoint works (/api/test) api related bot framework (/api/messages) not.

trying connect fiddler below information returns botauthenticator failed authenticate incoming request!

request sent: post: intranet:port/api/messages headers: accept: application/json content-type: application/json content-length: 532 host: intranet:port body: { "type": "message", "text": "hi", "from": { "id": "default-user", "name": "user" }, "locale": "en-us", "textformat": "plain", "timestamp": "", "channeldata": { "clientactivityid": "1503305115246.7002765593111311.0" }, "entities": [{ "type": "clientcapabilities", "requiresbotstate": true, "supportstts": true, "supportslistening": true }], "id": "ei7ck29k3jj2", "channelid": "emulator", "localtimestamp": "2017-08-21t11:45:19+03:00", "recipient": { "id": "4fn4lffkkb5heeam3", "name": "bot" }, "conversation": { "id": "5l5dn2diegck" }, "serviceurl": "http://localhost:port" } received:

then tried add authorization header token generated https://login.microsoftonline.com/botframework.com/oauth2/v2.0/token same problem persists. bot added skype business when sending message, reply on skype business online be: error happened in skype business service when reaching bot service.

we have used microsft appid , password settings of botframework in azure , included them in web.config

any thoughts?

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
