We review some basic flux vacua counting techniques and results, focusing on the distributions of properties over different regions of the landscape of string vacua and assessing the phenomenological implications. The topics we discuss include: an overview of how moduli are stabilized and how vacua are counted; the applicability of effective field theory; the uses of and differences between probabilistic and statistical analysis (and the relation to the anthropic principle); the distribution of various parameters on the landscape, including cosmological constant, gauge group rank, and SUSY-breaking scale; "friendly landscapes"; open string moduli; the (in)finiteness of the number of phenomenologically viable vacua; etc. At all points, we attempt to connect this study to the phenomenology of vacua which are experimentally viable.

We do not wish to go into it in any depth here but it is important to realize that what is known as The Measure Problem [ref] directly affects this work.

This involves extrapolating from that small corner of the string-theory landscape where computation is tractable [ref] . `Bottom-up' progress is being made by studying simple landscapes that can be understood completely, and increasing the complexity step by step.

Also, there is some evidence that string theory has a “landscape” of metastable vacua with varying cosmological constant, moduli VEVs (and therefore couplings), supersymmetry (SUSY) breaking scale, and so on, which can be studied using statistical arguments (see [ref] for reviews).
