Actually I should be working on my bachelor report (it's due tonight), but hey, there are more important things like: Can I omit the to in the following sentence?

... foster behaviour that would help the robot population (to) adapt to the MONEE environment.


When using the verb "help," you can use either a to-infinitive or a bare infinitive without affecting the meaning or the grammaticality of the sentence. The bare infinitive version is more common especially in American English.

"[...]the better practice is to use a bare infinitive after help (if the choice is between a fully expressed infinitive [with to] and a bare one [without to]) [...]

"The bare infinitive form after help overtook the to-form in the late 1960s and remains more than twice as common with various verbs."

Garner (2016), Garner's Modern English Usage. Oxford University Press.


As Cambridge dictionary says:

We use help with an object and an infinitive with or without to:

  • Jack is helping me to tidy my CDs. or Jack is helping me tidy my CDs.

Both “help someone do something” and “help someone to do something” are acceptable. The form without “to” seems to be more common in everyday speech than the form with “to(especially in American English), but both forms are common in formal writing. - jakubmarian.com

Judging by the Google Ngram "help something/somebody adapt" is far more common than "help something/somebody to adapt":
