Few cloud based EAs
SOFEA (Merelo et al.)
FlexGP (Sherry et al.)
EAs using Map/Reduce (Fazenda et al.)
EvoSpace (Garcia et al)
No specific Collaborative-IEA (C-IEA)
Big Companies offering Cloud services
Amazon EC2, Google Apps …
SaaS, PaaS, IaaS

7. EvoSpace
1.
The
EvoSpace
container
that
stores
the
evolving
population.
2.
Remote
clients
called
EvoWorkers,
which
execute
the
actual
evolutionary
process.
EvoSpace
consists
of
two
main
components
:

key-‐value
store
Keys
can
contain
strings,
hashes,lists,
sets,
sorted
sets.
In-‐memory
but
persistent
on
disk
database.
Single
threaded.
Master-‐slave
replication.

47. Efficient
implementation
of
Set
operations
needed
for
evospace:
Add,
remove,
and
test
for
existence
of
members
in
O(1).
Returning
and
removing
a
random
member
from
a
set
is
also
O(1).

48. Each
individual
is
a
unique
key
and
a
JSON
object
string.
ind:123
-‐>
{
chromosome:[0,1,0,1],
fitness:0.2}
A
Population
is
a
set
of
keys.
pop:1-‐>
{ind:123,
ind:124,
ind:13,
ind:132}
Samples
are
also
sets.
Re-‐Insertion
is
a
union
of
sets.
