finite automata - Advantages/Disadvantages of NFA over DFA and vice versa -

-

what relative pro's , con's of both dfa's , nfa's when compared each other?

i know dfa's easier implement nfa's , nfa's slower arrive @ accept state dfa's there other explicit, known advantages/disadvantages?

the advantage of nfa's on dfa's property, "choose right path". since cannot in algorithm "choose right path", conversion nfa dfa works, creating dfa states symbolize multiple nfa states. thus, when nfa in state , has choice go a,b or c next state in dfa {a,b,c}.

this explains advantages , disadvantages: dfa's can implemented easier since next state determined function. nfa's allow user easier express want, because nfa can choose between many path's.

pypdf throws exception: pypdf.utils.pdfreaderror: eof marker not found i don't need fix pypdf, need eof error cause "except" block execute , skip on file, doesn't work. still causes program stop running. background: batch ocr program pdfs python, pypdf, adobe pdf ocr error: unsupported filter /lzwdecode ... saga continues. i got 10,000 pdfs in folder. ocrd, not. can't tell 'em apart. step 1 figure out ones not ocrd , ocr (see other threads details). so i'm using pypdf. exceptions related unrecognized characters , unsupported filters when try read text. guestimated if throws exception, it's got text in , doens't go in list. problem solved, right? so: pypdf import pdffilewriter, pdffilereader import sys, os, pypdf, re path = 'c:\users\homer\documents\my pdfs' filelist = os.listdir(path) has_text_list = [] does_not_have_text_list = [] pdf_name in filelist: pdf_file
