You certainly may omit the "is" but you may also add it back to the sentence to emphasize the situation.
The leading clause "the better the program (is)" is an adverb modifying the main clause "the more will come".
However, you should not omit regular verbs. For example...
The longer the program runs, the more will come. (You should NOT omit "runs".)
所以,一般來說,在這一種結構的句子中 be動詞,是可以省略的(除非你是要強調). 但是其他動詞就不應該省略.
例子們:
The bigger (it is), the better (it will be).
The taller (he is,) the more handsome he becomes.
The less she runs, the harder she breaths.
