It appears in section 1 of the PDF of the bill where it is explaining the legislative intent.

The summary and justification sections help set the intent of the bill, but they don't define the law itself.

Those uses are:

    Section two of this bill adds a new Article 45-A to General Business Law
    to require addictive social media platforms which feature predatory
    features such as algorithmic feeds, push notifications, autoplay, infi-
    nite scroll, and/or like counts as a significant part of the provision
    of their service to post warning labels for all users upon access to the
    platform. The bill features a series of specific exemptions for certain
    types of notifications that fall beyond the scope of the bill (i.e.
    those explicitly requested by a user or which are deployed for civic
    communication). More broadly, the bill also exempts any feature which is
    determined by the Attorney General via regulation to be offered for a
    valid purpose unrelated to prolonging use of the addictive social media
    platform.

    ...

    ...             Additionally, as this bill covers only social media
    platforms that deploy addictive features such as algorithmic feeds, push
    notifications, autoplay, infinite scroll, and like counts, any platform
    not wishing to display a warning label could simply limit their use of
    these features.
The text of the law, however, does not define "algorithmic feed" (sorting by date post could be considered "an algorithm" by some).

"[S]uch as algorithmic feeds" in the description and justification remains undefined in the text of the bill itself.
