Some Easy Theorems in Kolmogorov Theory Exposition by William Gasarch (gasarch@cs.umd.edu) 1 Introduction Intuitively the string 00000000000000000000000000000000000000000000000000000000000000000000 is not random. Note that you could write a program of length O(log n) that print out 0n. Intuitively the string 01101000110000001110101010001100011010010010101001010110101010111110000 is random. The shortest program to print it out might just be print(01101000110000001110101010001100011010010010101001010110101010111110000) which is of
