finite automata - Moore Machines with n states -


i working on end of chapter question regarding how many different moore machines there n states. n = number of states, m = number of input letters, , q = number of output characters, correct there n*q^m possible machines? reasoning each state, each input has possibility lead 1 of give output characters.

a moore machine consists of:

  • set of states s (n)
  • start state s0
  • input alphabet sigma (m)
  • output alphabet (q)
  • transition function (s x sigma -> s)
  • output function (s -> a)

the number of states , input/output-characters given.

for start state there n possibilities.

for transition function, there |s| ^ (|s| * |sigma|) = n^(n*m) different variants.

finally, there |a| ^ |s| = q^n output functions

this yields in total n^(n*m+1) * q^n different moore machines.

caching - How to check if a url path exists in the service worker cache -

i need check if particular url path exists in service worker cache. example, suppose url is: /myserviceworker/service?a=110&b=70 this url exists in cache, there many of them different values of , b. now, suppose want refresh of these urls, how can that? i want know how access key values service worker cache. if know key, plan follows: var url = new url(key); if(url.pathname === "\/myserviceworker/service") refetch key but not sure how cache key , in format is. mean, string or url? cache api has match() method returns promise resolving in response object if match or undefined if no match exists. second parameter object can specify ignoresearch not take account url parameters. the ignoresearch option supported firefox ( chrome status here ). in other hand, retrieve cache entries, can use keys() method.

Redirect to a HTTPS version using .htaccess -

i need modify .htaccess file redirect urls https version without "www". http://example.com --> https://example.com http://www.example.com --> https://example.com https://www.example.com --> https://example.com this how .htaccess file looks like: rewriteengine on rewritecond %{request_filename} !-d rewritecond %{request_filename} !-f rewriterule ^(.*)$ redirect.php?id=$1&page=$2 [qsa,l] what modifications need make .htaccess in order forward https without "www"? it depends on doing current code. looks file called redirect trying display php page seo friendly url. think might confusing people. anyway, need , force https without www, need 1 more rule above. also second rule needs two capture groups in rewriterule test string because wanting 2 different values using $1 , $2 references. rewriteengine on #rediect www non www and/or http https --- combinations. rewritecond %{http_host} !^example\.com [nc,or] rewritecond %{https} !^
